Introduction and News
Welcome to the website of the Upper Thames Branch
of Butterfly Conservation. Founded in 1982, the Branch aims to protect butterflies,
moths and their habitats in the three counties of Berkshire, Buckinghamshire &
Oxfordshire, which includes the beautiful rolling hills of the open Downs and
wooded Chilterns, the broad vales of Oxford and Aylesbury with the ancient
Bernwood complex, the edge of the picturesque Cotswolds and the threatened
heathlands of south-east Berkshire. We have some 800 members and the Branch
is managed by the membership on an entirely voluntary basis.
The three counties are home to three quarters of the 60 or so British species
of butterfly and two thirds of the 900 or so British macro-moths.
Most notable amongst the butterflies are the Black Hairstreak,
with half the UK colonies being found in Buckinghamshire and Oxfordshire, and
the Adonis Blue and Silver-spotted Skipper, with their most
northerly UK populations in the Chilterns.
Amongst the macro-moths Buckinghamshire is
considered to be one of the strongholds of the Striped Lychnis,
a population of the Heart Moth is to be found in Berkshire and
colonies of the Barberry Carpet and Pale Shining Brown have
recently been discovered in west Oxfordshire.
Thanks to the generosity of Beaconsfield Town Council the Branch has its own reserve
at Holtspur Bottom in Bucks. Here we have transformed the northern side of Holtspur Valley
from derelict agricultural land back to species rich chalk grassland and over the last
few years the Green Hairstreak, Small Blue, Dark Green Fritillary, Chalkhill Blue
and Striped Lychnis have all been recorded here. A report by Nick Bowles and
Frank Banyard in the Conservation section will update you on the success of the
Small Blue in the Holtspur Valley. If you would like to visit our reserve then the
location can be found in the Sites section.
The Branch regularly monitors the butterflies and moths within the three counties.
We have published two butterfly atlases in 1994 and 2005 and both are still available.
Our rare species all receive special attention through our
Species Champion programme.
During the winter we carry out conservation work at several sites, including regular work parties
at our own reserve, and we arrange a limited number of indoor events. Most notable amongst
these are our Members' Day in late October or early November and our Conservation
Action Day in February or March. During the spring and summer we have a programme of
Field Meetings across the three counties. You can find details of our programme in
the Events section.
Butterfly and/or moth records from non-members are very welcome and information
on submitting them is given in our Your Records
section. Non-members are also very welcome to attend any of our events which are listed
on the Events page.
If you would like to become a member of Butterfly Conservation you will
receive the national magazine, Butterfly, and automatic membership of the
Upper Thames Branch if you live in the area. You will also receive our Branch newsletter
which is produced three times a year. Please

Thank you to Maureen Cross for 25 years as UTB Newsletter Editor!
By Jim Asher
"Maureen Cross recently gave her formal notice as Editor of the branch News. Maureen has done the job
unstintingly since 1989 - a continuous period of 25 years - since she took over from the previous editor, one
David Redhead! That is a truly amazing contribution - we are all hugely grateful for what she has done
and wish her some well-justified relief from the task and more time to watch butterflies."
Jim Asher presents Maureen Cross with a painting at UTB's AGM on 25th October 2014.
The painting was produced by Richard Lewington (centre) and is a unique picture depicting
the life-cycle of Adonis Blue against a background of Lardon Chase -
the slope where they normally fly.

Apology & Thank You to Chris Dennis
We wish to apologise that under the photograph “New Entrance Sign at Holtspur” in the recent
newsletter (September 2014 edition) we credited Steven Daniell (pictured with the signboard) and
John Saggerson. We should have made it clear that while they designed and cut the lettering, all
costs were met by Chris Dennis (UTB member and owner of G & MB Manning Ltd, specialist
Agricultural and Fencing suppliers). It was Chris who sourced and paid for the materials, then
organised and paid for the engraving of the letters and delivery.
We are glad to redress that oversight and publicly acknowledge the tremendous support that Chris
has given the Upper Thames branch on a number of occasions over a very long time.
Jim Asher elected as the next National Chair of Trustees for BC - announcement by David Dennis:
I am delighted to announce that on March 8th, Council unanimously elected Dr Jim Asher as the next
National Chair of Trustees for BC. The handover will officially take place at this year's AGM on
November 15th. There will be further announcements later in the year concerning the roles of Vice-Chair
and Chair of Conservation Committee, both currently held by Jim.
Jim Asher will be well known to most of you as a long-standing conservationist, volunteer and
Chair of Upper Thames Branch, in addition to his national work. He played a leading role in the
Millennium Atlas project and in subsequent publications. He is also the butterfly photographer I
least like to be in competition with at our Branch Members' Day!
I'm sure you will join me in sending Jim many congratulations and best wishes. The next few years of
Butterfly Conservation's 2020 Vision development could not be in better hands.
With very best wishes
UTB donation helps save Meadow Farm!
BC Upper Thames Branch donated £1,000 to an appeal by the Wildlife Trust to save Meadow Farm. The following press
release went out on 19th December:
"Meadow Farm, a precious remnant of ancient wildflower meadows, near Blackthorn on the border of Oxfordshire
and Buckinghamshire, will be open to visitors in 2014, thanks to a grant from the Heritage Lottery Fund.
On 6 December the Heritage Lottery Fund awarded a grant of £758,000 to the Berks, Bucks & Oxon Wildlife Trust (BBOWT). This means that Meadow Farm will be bought by the Wildlife Trust to establish a three-year project of events and activities at the wildlife site involving local communities and schoolchildren.
Earlier this year over 2,000 people donated £270,000 to an appeal by the Wildlife Trust to buy Meadow Farm. BBOWT chief executive Philippa Lyons paid tribute to the donors. “I am very grateful to everyone who gave so generously. Their contributions provided the matched funding for the Heritage Lottery Fund grant. They have secured the future for Meadow Farm as a very special wildlife haven for local people to enjoy forever.
"The real work starts in the New Year with recruiting the project manager, and then planning a series of exciting community activities and events to take place in the summer, so that residents and schoolchildren from Bicester, Aylesbury and the villages of the Upper Ray can discover the beauty of this wildlife haven for themselves," said Philippa Lyons.
Across the whole of the UK there are only 1,500 hectares of floodplain wildflower meadows like Meadow Farm. Philippa Lyons added: “Meadow Farm has irreplaceable wildlife habitats that are vital for insects, butterflies and wetland birds such as the curlew. Otters are known to be using the River Ray along the northern boundary and the overgrown hedgerows are superb habitats for the rare black and brown hairstreak butterflies.”
Stuart McLeod, Head of Heritage Lottery Fund South East England, said: “We are delighted to support this project to conserve what is nothing less than an oasis of biodiversity for Oxfordshire and Buckinghamshire. This area of flower meadow that has lain undisturbed for centuries can now be fully protected while providing a valuable learning resource.”

Are Exotic Continental Butterflies and Moths Colonising the UK? - Butterfly Conservation
Exotic butterflies and moths from the Continent are attempting to colonise the UK following this
year’s warm summer and mild autumn.
The Long-tailed Blue, a rare migrant butterfly from Europe, has raised broods at several
sites across the south coast of England and very rare migrant moths the Clifden Nonpareil and
Rosy Underwing have been seen in increasing numbers in recent weeks across several southern counties.
These sightings suggest that all three species may be attempting to colonise southern England and come
as the autumn moth migration gets into full swing bringing rarities such as the Crimson Speckled
and the Vestal to our shores from Southern Europe.
Long-tailed Blues migrated to the south coast in August and in the last fortnight the first
home-grown British adults have emerged with the butterflies seen at sites including Dover and Margate in
Kent and Newhaven in Sussex and a site in Wiltshire. The butterfly has bred in the UK on a handful of
occasions before but this summer is the first time the Long-tailed Blue has raised young over such
a considerable area.
Dramatic-looking Continental moths are also believed to be colonising the UK with recent multiple sightings
of the beautiful Clifden Nonpareil in Dorset, Hampshire and Sussex. The Clifden Nonpareil is the
largest and most magnificent of the underwing moths, a group that sport vivid underwing flashes they
use to ward off predators. The moth, which boasts a striking blue wing flash, was first recorded in
There has also been a recent increase in sightings of the very rare migrant - the Rosy Underwing.
Prior to this summer, this large moth has only been seen on 10 occasions in Britain. The latest sightings
raise the tantalising prospect that the moth is now locally resident.
Butterfly Conservation Surveys Manager Richard Fox, said: “These sightings are very exciting news, not
only for the people lucky enough to see these thrilling butterflies and moths in the wild but also for
“The hot summer enabled Long-tailed Blues and other migratory butterflies to spread northwards into
Britain, capitalising on opportunities to breed here while the weather remains warm.
“This species probably won’t survive the forthcoming winter, but it seems likely that the stunning
Clifden Nonpareil and possibly even the Rosy Underwing, have already established footholds in southern
Dorset County Moth Recorder Les Hill has seen three separate Clifden Nonpareil moths in the past two
weeks in the same part of south Dorset. He said: “Clifden Nonpareil is one of the most charismatic of
British moth fauna and is on every moth recorders’ ‘wish list’. As the name nonpareil states, it is
peerless and has no equal. To record one in a lifetime is the fulfilment of an ambition; to record
them every year in my garden is just remarkable.”
The traditional autumn moth migration is now well underway with the largest number of Vestal
moths entering the UK for half a century. The delicately patterned Vestal is typically found in
North Africa and Southern Europe and this autumn has been found as far north as Scotland and
Higher than average numbers of the exotic Crimson Speckled moth, which is usually found in
North Africa and Southern Europe, have also been recorded along the south coast.

You will be aware from recent media that Ash Die-back has been found quite widely across Britain
in the last few weeks. It is potentially a big threat not just to ash trees but also to the
30+ moths that feed on ash and a few other butterflies that use ash for mate location and to
feed on honeydew (eg Brown Hairstreak).

New Green Hairstreak aberration discovered in Buckinghamshire - article by Wendy Campbell
In April 2011 Chris & Pat Dennis of Princes Risborough photographed a Green Hairstreak
with unusual markings at a Wildlife Trust site in Bucks and sent the photograph to
the Upper Thames Branch Website for inclusion in our Butterfly Sightings page.
Callophrys rubi ab. dennisorum

(click photo for larger image)
||Chris & Pat noticed that the white 'hairstreak' markings on
the underside of the hind wings were unusually well developed and distinctly enlarged.
Unable to find anything similar in the British Natural History Museum's on-line Cockayne
database, I forwarded the photo to Piers Vigus, an amateur lepidopterist with a particular
interest in aberrations and he subsequently sent a copy of the image to the Natural History
Museum for identification. Staff there couldn't find any specimens in the British collection that
resembled the discovery, nor could a similar specimen be found in the foreign collections
and Geoff Martin, Collections Manager, therefore confirmed that to his knowledge this
aberration was as yet totally undescribed.
In accordance with established convention, Chris & Pat were given the honour of naming
their newly discovered aberration and chose: Callophrys rubi ab. dennisorum.
The next step in naming the new aberration was to write a technical Note for publication
in a well known and respected entomological journal. After further rigorous checks, Colin Plant
published my Note in The Entomologist's Record in September 2011, officially naming the

An urgent request from Martin Warren, Chief Executive of
Natural England Grant Cuts - CALL FOR HELP
Martin Warren, Chief Executive of Butterfly Conservation, has issued the following memo to all Branches:
Dear Branch Chairman (cc Branch contacts in England)
I am writing to ask for the help of you and your Branch in fighting the severe cuts we have had to our
Species Recovery Grant from Natural England. I am sorry that we feel we have to take this action, but having
discussed it with senior staff and key Council members, we feel that it is vital to make our voice heard.
For the last 16 years we have received a grant from NE (and its predecessor) for work to save our most
threatened butterflies and moths. Under these grants we wrote our first Species Action Plans and Regional Action Plans
which have guided BC’s conservation effort for the last 15 years, in harmony with government priorities of the
UK Biodiversity Action Plan (BAP). We have also employed some wonderful expert staff who have conducted vital
research on species, given advice to landowners of hundreds of key sites, written species accounts and
management guidelines, developed landscape projects, raised millions of pounds for conservation, and supported
our volunteer network in a myriad of ways.
For reasons that have not been properly explained, NE have decided this year to greatly reduce their grant to
BC from £300K pa to £40K, the latter just to work on a small number of very rare moths. This amounts to a cut
of 85% to our core work, which is part of the 30% cuts that NE are facing over the next 3 years, they made around
400 people redundant this April and another 400 will have to go next year. However, they have made disproportionate
cuts to our grant and a big cut of at least 50% to their Species Recovery Programme.
At least one of the factors driving this is the new England Biodiversity Strategy (EBS) which puts much less emphasis
on species conservation and more on habitat conservation and landscape/ecosystem. We have pointed out in the
strongest possible terms that such initiatives will not work for threatened species without specialist input of
our staff and volunteers, but so far this has fallen on deaf ears.
The cuts have put BC in a very difficult position and we had to make 2 conservation staff redundant earlier this
year. We are using our financial reserves to retain as many staff as possible this year, but may have to make more
redundancies next year if we cannot replace this c.250K of lost income. Although membership has increased well
this year, to around 17,000, much of this has been for half price offers and does not bring us in a great net
income in the short term.
We are working with other species NGOs to raise our concerns at Ministerial level (eg RSPB, Plantlife, Buglife,
Amphibean and Reptile Conservation) but feel we need to express the same concern at local, grassroots level. The
new EBS says that it wants to work in partnership with NGOs, and increase the engagement of local groups (the
Big Society), but the cuts seem to be sending out a completely opposite message.
Hence we are asking you to write to your local MPs expressing your concern about these cuts and how they will risk
further decline of threatened species and disempower local volunteers such as yourselves. I am attaching a template
letter that you can use and adapt as you wish.
We are still having talks with NE and have some strong support from senior conservationists who have written on
our behalf. However, your action will be extremely helpful to underline the strength of feeling from our
Thank you in advance for any help you can give to help this dire situation.

An urgent request from Martin Warren, Chief Executive of Butterfly Conservation
A very worrying consultation has recently been announced by Government which is considering the scrapping
of various environmental laws. I am emailing Branch committee members to ask you to express your opposition
to this proposal which could do immeasurable damage to wildlife, including butterflies and moths. Please
circulate this email to anyone else who might feel the same.
If you have 30 seconds
Sign the online petition set up by 38 degrees
If you have 2 minutes
Register your views on the Government website
The Government has recently launched a consultation on the proposed scrapping of a whole range of regulations,
known as the “Red Tape Challenge”. This was launched by Vince Cable on 7 April 2011 in a bid to boost
short-term economic growth. Amazingly this includes most of the wildlife legislation that we and our partners
have worked so hard to get on the statute books in recent years.
In short, it seems Government is considering getting rid of the Wildlife and Countryside Act, the Climate Change
Act, and 278 environment laws (among thousands of laws and regulations). These Acts are essential for
protecting key wildlife sites and species from development and have been developed after long campaigns by
wildlife NGOs. Scrapping them would result in immeasurable damage to species and habitats, including butterflies
Environmental regulations fall under “general regulations” on which the Government are inviting comments
throughout the process. The Cabinet Office is ‘crowdsourcing’ proposals for which laws should be scrapped,
with Ministers facing a basic presumption that laws and regulations listed in the Red Tape Challenge should
be scrapped. Once the nation has had its say, Ministers will have three months to work out which regulations
they want to keep and why.
The Government’s website invites comments either as an individual or as an organisation, about the need
to protect our environment. The website lists the 278 environmental regulations under scrutiny and your
comments can be left under 7 broad headings.
My own contribution reads
“The Government has only just signed the new UN target set at Nagoya to halt biodiversity loss and restore
ecosystems by 2020. It simply cannot honour this commitment if it scraps its own wildlife laws.
Biodiversity is essential to life on earth and needs protection.”
Thank you very much for your support.

Newsletter 81 (February 2011) - Garden Survey Report for 2010 - Margaret Price
Due to a misunderstanding the wording in one particular section of the report relating to the completion
of the survey form is not clear. The sentence which reads: ‘It has been decided not to drop use of
the letter system for recording in favour of the actual number of each species seen at any one time ...’
should read: ‘It has been decided not to use the letter system for recording but the actual number of each
species seen at any one time ...’ This has been reflected in the latest version of the Garden Survey 2011

Oxford Brookes University Science Bazaar went with flying colours!
As part of the Oxfordshire Science Festival, Butterfly Conservation members Casper Breuker
(Oxford Brookes University) and Melanie Gibbs (Centre for Ecology & Hydrology, Wallingford)
hosted 'The ABC of Amazing Butterfly Colours' at the
Oxford Brookes University Science Bazaar
on Saturday the 12th of March 2011. The bazaar was part of the National Science Week, with the
aim of getting young children excited about nature and science. Equipped with a variety of
brochures provided by Butterfly Conservation, including 'Caterpillars a brief guide' and
'All about moths', Casper and Melanie told the children, and their parents, all about the
amazing colour patterns found on caterpillars and on the wings of moths and butterflies and
explained the importance of these patterns for camouflage, thermoregulation, mate choice and
predator avoidance. Furthermore, they explained what kinds of butterfly research people do, and why.
The children learned that humans are destroying and modifying the landscape with the result that,
for example, butterflies and moths may be required to travel over larger distances in search of
plants to lay their eggs on. Melanie and Casper presented the visitors at the science bazaar with
the recent results of a collaborative research project between Oxford Brookes University and CEH
Wallingford, showing that when female Speckled Wood butterflies (Pararge aegeria) need to fly more
to find resources and plants for egg laying, they lay smaller eggs. These smaller eggs do not
always hatch and the caterpillars that do hatch from these small eggs grow slowly and may be
more susceptible to diseases (Gibbs et al 2010a,b). The children were very keen to help butterflies
and moths and were most keen to use the Butterfly Conservation brochure 'Gardening for Butterflies'
to provide extra resources for butterflies and moths in their gardens. Overall, more than 200 people
attended the science bazaar, and great fun was had by all! This event will be run again in 2012.

The Wider Countryside Butterfly Survey (WCBS) continues in 2011 - by
Dr Zoë Randle, Surveys Officer
Once again this will be a collaborative project with BTO and CEH. We would like to thank everyone
who took part last year and especially the WCBS Champions who helped promote the survey within the
Branches. The survey had another successful year with nearly 700 squares sampled. We hope you
will continue to survey the same squares in the same way as last year. Our priority is to re-survey
these squares for at least the next 2 years so that we can determine trends in the wider countryside
and see whether they differ from transect trends. We also welcome new participants either to help
re-survey old squares, or to survey new ones for the first time. New surveyors will be allocated
randomly selected 1-km squares in their Branch area. The squares need to be surveyed in July and
August by two visits at least ten days apart. Anyone interested in taking part in the WCBS in
Berkshire, Buckinghamshire or Oxfordshire in the coming season should contact
(the Upper Thames Branch WCBS Champion) for further information.

||Butterfly Transects: HELP REQUIRED!
Butterfly Transects are carried out at a large number of sites in the UK each year. The standard
method for carrying out the Transect (sometimes called a "Pollard Walk") was devised in 1973 by
Ernie Pollard at the Centre for Ecology and Hydrology and involves a walk along a fixed route at a
specific site. It is completed in suitable weather conditions each week between April and September
and involves counting the number of individuals of each butterfly species seen. At the end of the
year the data is collected together by our Transect Co-ordinator Mike Wilkins and sent off to BC and
to the CEH where it is used in the essential work of monitoring trends in butterfly populations.
You can read the UTB Reports for 2007-2010 by going to the
Transects are walked at more than 60 sites each year within the Upper Thames region. A few are
completed by one person, which can be quite a commitment, but many others are carried out by small
groups of individuals meaning that the workload is shared and may involve each person completing the
walk only once or twice a month. No particular expertise is required other than knowing the route
(training will be given) and being able to recognise and record the butterflies seen.
We currently have a vacancy in the team of three who cover the Transect in Waterperry Wood, Oxon (part
of the Bernwood Forest complex on the Bucks/Oxon border to the NE of Oxford). Could you spare around
90 minutes every three weeks to record butterflies there? If you can, Black, Brown and Purple Hairstreak,
White Admiral and Purple Emperor would be amongst the delights awaiting you at the site! If you can
help with this specific request, or would like to offer your services elsewhere in our three counties
as there may be other teams who would also appreciate an additional member, please contact

Paul Wetton spent six months in 2010 travelling from the south coast of England to western Scotland,
capturing the fifty eight breeding butterfly species of mainland Britain on film. This personal
account shows these fascinating and colourful insects, all filmed on location in Britain, using

Pete Eeles, UK Butterflies webmaster and Chairman of the Hampshire and Isle of Wight branch
of Butterfly Conservation, has reviewed the DVD set and says "I've reviewed a few DVDs of British
butterflies over the years and, I have to say, in terms of the quality of the footage, this production
is definitely the best and is what sets this DVD apart from the others. In addition, some of the
footage is quite unique - such as an episode where a couple of Purple Hairstreak seem to be clashing
over a particular oak bud. Very strange! The footage is complemented with Paul's own narrative which

UTB Member Becky Woodell receives the BC 2009 Outstanding Volunteer Award.
Becky is a founder member of the Upper Thames Branch of Butterfly Conservation and is also its
Wood White Champion. However, her main contribution to the well-being of our lepidoptera has been
through Whitecross Green Wood, a local Wildlife Trust reserve. Becky was highly instrumental in the
Trust securing the site in the early 70’s and since then has acted as its voluntary Warden,
playing a leading role in determining and carrying out the site management. In spite of being in

site which attracts visitors from across the UK. During 2009 she has played a leading role in assessing
the implications of the proposed re-opening of the Oxford to Milton Keynes railway line which was
known to be home to colonies of Wood White, Grizzled Skipper and Dingy Skipper. The investigations
inspired by Becky have also brought to light that a previously unknown Black Hairstreak colony is

Sheepdrove Rare Butterfly Project needs volunteers to monitor and boost project progress.
The Upper Thames Branch of Butterfly Conservation is a founding partner of the
Sheepdrove Rare Butterfly Project,
which has ambitious plans to bring priority species back to Sheepdrove Organic Farm, located on the border of
Oxfordshire and Berkshire. With help from local nature fans and the farm’s cattle, new habitat is being created
to suit Marsh Fritillary, Small Blue, Chalkhill Blue and more. Hundreds of caterpillar host plants are being
invested at key plots.
"We aim to establish the most southern colony of Marsh Fritillary in Oxfordshire and the second colony
known in Berkshire, where it is almost extinct.” explains Jason Ball, who devised the project, co-funded by
Natural England and the farm.
The farm needs volunteers to monitor and boost project progress and 2 survey transects are up for grabs!
Please contact Jason on 01488 674727 or email firstname.lastname@example.org.

Andrew Masterton of south-west Scotland branch is calling for help with
some important surveys of Priority butterflies in south-west Scotland. They are Pearl-bordered Fritillary,
Chequered Skipper, Mountain Ringlet, Dingy Skipper, Northern Brown Argus. Andrew has developed a marvellous
website with interactive maps to show you where the colonies are that he wants re-surveyed. All records
are to be sent to him via the website:
This is a vast area, in a beautiful part of Scotland, with some very important colonies so any help would
be greatly appreciated. If you know somebody who is visiting this area please pass this link on.

Stuart Hodges receives Outstanding Volunteer Award at BC's national AGM in York
For the last decade Stuart Hodges has been the Upper Thames Branch Black Hairstreak Champion and in this role
has been an exemplar for other Species Champions. His work has greatly enhanced our understanding and
conservation of the Black Hairstreak. It has directly led to not only the re-confirmation of several
historic colonies which were thought to be extinct but also to the discovery of a number of new colonies.
He regularly liaises with the relevant landowners to ensure the continuing well-being of the colonies
on their land and as a result several now take a positive and active pride in their colonies.
On 22nd November 2008 Stuart's achievements were recognised when he was presented with an
Outstanding Volunteer Award by Chairman Maurice Avent at BC's national AGM in York.

The Wider Countryside Butterfly Survey (WCBS) goes ahead in 2009
by Dr Katie Cruickshanks, WCBS co-ordinator
After two years of pilot testing, a new method of monitoring butterflies in widespread habitats, such as
farmland and upland moorland, is to be rolled out nationwide this year. The Wider Countryside Butterfly Survey method has been developed by Butterfly Conservation and the Centre
for Ecology and Hydrology as part of the UKBMS project. The existing Transect network provides invaluable data on the status of butterflies, yet widespread habitats
are under-recorded. More information on the fate of butterflies in these areas is needed. The new survey is
intended to fill these gaps by complementing, rather than replacing, the existing Transect network.
The pilot testing has thrown up some interesting information. Last year, despite the unsettled weather, nearly
two thirds of the 1-km squares visited in 2007 were revisited by volunteers. In total 40 species were recorded.
Importantly all 23 target species were detected in both pilot years which means that trends can be analysed to
test whether classic Transects provide a truly representative picture of butterflies in the UK landscape as a whole.
Volunteers who have participated in the pilot testing have shown considerable enthusiasm and it is hoped this will
continue to grow. There has been close involvement with the British Trust for Ornithology and the method is based on the highly
successful Breeding Bird Survey. We hope that many BTO recorders will be returning to their bird sites this summer
to collect butterfly data as part of the survey along with many new surveys completed by BC recorders.
The new method involves making a minimum of two visits to a randomly selected square near to your home between
May and August to count butterflies along two 1km survey lines running roughly north-south through the your square.
The survey will be co-ordinated centrally by BC but we aim to find a Champion in each Branch to help find willing
volunteers. We are aiming for 20 squares per Branch.
Please email email@example.com or call 01929 406036 to register interest in taking part and you
will be contacted in early spring with instructions and the location of your random 1km survey square. Keep an eye
for more information.
BC National Recorders’ Meeting: Saturday 4th April 2009
Booking is now open for the 2009 National Butterfly Recorders’ Meeting. It will take place once again at the
Birmingham and Midland Institute, Margaret Street, Birmingham B3 3BS (see www.bmi.org.uk for a map). The
National Recorders’ Meeting provides key feedback to volunteers about the butterfly recording and monitoring
undertaken through national projects – Butterflies for the New Millennium and the UK Butterfly Monitoring Scheme.
Butterfly population trends for 2008 will be unveiled for the first time at the meeting and we will also hear
about the launch of the Wider Countryside Butterfly Survey in 2009. Guest speakers will give presentations about
several exciting butterfly projects making use of recording and monitoring data, including research into the
decline of the Small Tortoiseshell by Owen Lewis (Oxford University). We do require advanced booking for this
event and there is a (heavily subsidised) registration fee of £5 per person, which will be collected on the day,
to help cover the costs of venue hire, tea/coffee and buffet lunch. If you would like to book a place please
contact Ian Middlebrook at Butterfly Conservation providing your name and contact details (Telephone 01929 400209
or Email firstname.lastname@example.org).
National Moth Night is on 18th and 19th September 2009
Recording can take place on either night or on both. There are no target species, but the theme is migration and we are
planning some exciting activities. More details will follow later in the year.
National AGM / Members Day – Saturday 21 November 2009
This year’s BC AGM and Members Day will take place on Saturday 21 November at Winchester University and
will be hosted by Hampshire & IOW Branch. Further details will be available later in the year.
International Symposium – March 2010
Butterfly Conservation will be holding its 6th International Symposium on 26-28 March 2010 at Reading
University. The meeting will address the key target of halting biodiversity loss by 2010 which was set across
Europe almost a decade ago. There will be reviews of progress from the UK, Europe, and countries throughout
the world, as well as the latest science on how to reverse declines and conserve habitats. The Symposium
will conclude with an analysis of future challenges, including the impact of climate change. Further
information and details of how to book will be posted on BC’s national website over the coming months.

MPs alarmed at butterfly declines - BC member and MP Bob Russell has produced an
Early Day Motion which calls on Government departments to work co-operatively to help our beleaguered
butterflies. He already has over 50 signatures from other MPs but your local MP might not have signed.
Please visit this link to see the Early Day Motion (EDM 8):
Assuming you find this a sensible and positive proposal, please write to your MP.
Even as few as 10 letters, on any one subject, will tend to dominate their correspondence and certainly make
them think. An EDM which attracts large numbers of signatures is still unlikely to be debated in the House
of Commons but just might be. They certainly alert the Government to the strength of feeling of the members
(across all parties). For this reason they are assumed to impact on Government direction. There is a
sample letter here (Word document)
or here (plain text document)
that you can download and use as a basis for your own. Of course, if your MP has signed then equally we wish to thank them. More details are
available on the
BC Head Office website, where you can also find the name of your local MP.

Butterfly Week on BBC1's One Show next week (each night,
from Monday 25th - Friday 29th August), will be presented by Miranda Krestovnikoff with
contributions from Matthew Oates, National Trust. It will star the Large Blue at Collard Hill, an almost
unsuccessful pursuit of the Swallowtail in the Broads (note that the larva shown is not a
Swallowtail), a good performance from the High Brown Fritillary at Heddon Valley,
Cabbage Whites etc. at Barrington Court garden, Soms, and best of all, Friday 29th:
The Emperor's Breakfast, in Fermyn Woods. Do not miss the latter, it is Matthew Oates'
personal fantasy acted out and shows that when it comes to eccentricity British natural history
still has what it takes...
20th June 2008
As a way of celebrating the 40th anniversary of Butterfly Conservation,
the Gloucestershire Branch has produced a booklet of 40 good butterfly walks in the county.
"40 Butterfly Walks in Gloucestershire" has even made members of the committee want to go out
and visit places they have never been to before! About 25 members of the branch have contributed
the walks and the whole project was co-ordinated by Roger Wasley. It is hoped that other people
will find the booklet useful and that it will heighten their interest in butterflies and the
countryside around them. As Matthew Oates says in his Forward 'This book opens up some of the most
wonderful English butterfly walks imaginable. Enjoy, and engage!'
The price is £4.50 to include postage and packing and details of how to order your copy are
available on the Homepage of the BC Gloucestershire Branch website:

A UTB Conservation & Publicity Success - In
September 2006 the Upper Thames Branch (UTB) was involved in the refurbishment of
a small area in Wood Farm Estate, Oxford as part of the ITV Big Clean-up Campaign
organised by the Conservation Volunteer Service (CSV). One element of this was the
planting of a new hedge and blackthorn was included at the request of UTB as the
Brown Hairstreak was known to be within 1km of the site. UTB members Caroline Steel,
Jim Asher and David Redhead joined local residents in helping to plant the hedge.
We are now very proud to announce that last summer a Brown Hairstreak found this
new hedge and laid three eggs on it. The CSV Press Office announced this via a press
release this morning (Monday 12th May) and this afternoon UTB Brown Hairstreak
Champion, David Redhead, spent some time at the site with the Oxford Mail & Times
photographer getting pictures of the 5mm long caterpillar which had emerged from
one of these eggs. Hopefully, it will also be figuring on ITV local news in the
next few days.
Update 16/05/07: An article appeared in the Oxford Mail
on 13th May and is currently available to read on the internet at the following link:
The article may be largely repeated in the weekly sister publication on Friday 16th May,
the Oxford Times.

A new White-letter Hairstreak Recording Project has
been initiated by the Herts & Middlesex branch of Butterfly Conservation.
This three-year nationwide project aims to discover the distribution of
the White-letter Hairstreak Butterfly. It has two distinct phases: locating
flowering elm in springtime and looking for active males in the treetops
at the start of the flight period.
If you would like to help, or would just like to learn more about this fascinating
butterfly, visit the following excellent website:
