Much of our winter effort is at our own Holtspur Bottom reserve near Beaconsfield, and we work also at Aston Upthorpe in Oxfordshire.

You might combine a walk around the site with a brief session of work. Nobody has to work for the entire session but obviously you may. There are a variety of tasks and no great strength is required. Tools and full instructions are provided.
Please bring stout footwear, a drink and a snack.

All work parties start at 10.00 a.m. unless otherwise stated. At both sites we usually finish about 13.00, although in good weather conditions we may continue until about 14.00.

PLEASE, ALWAYS CONTACT THE TASK LEADER IN ADVANCE and check also for any updates on the branch website, as details frequently change according to weather, number of volunteers, etc.

Because the adult Brown Hairstreak is quite an elusive beast, looking for eggs on blackthorn during the winter months is the best way to map the distribution of the species. A limited number of sites, spread across our local population, are also visited annually by a group of us and searched thoroughly, the results enabling the Branch to monitor the health of the butterfly from year to year.

Anyone is very welcome to join us - no previous experience is required! It would be useful if you could bring a hand lens (x10) or small magnifying glass but otherwise no equipment is needed. Please wear warm clothing and waterproof footwear. It is also a good idea to bring a warm drink to revive you after a couple of hours in the field.

In the past the weather or other circumstances beyond our control have sometimes caused a search to be cancelled, occasionally at the last minute, so if you do intend to join us it is important that you please let Dave Wilton know by the evening before, preferably by e-mail to wilton@burnhamlodge.plus.com (otherwise via text or telephone to 07751 472004). Where changes are known about in sufficient time, information will be posted on this website.

This winter's programme of searches will include the following:


Sunday 16th November 2014 - Slade Camp, Shotover, Oxford (10.30am - 1pm)

Meet in the retail car-park at grid reference SP555050 on the west side of the A4142 Oxford Eastern By-pass (turn off the A4142 at the Horspath Driftway traffic lights then take the first left into the retail park). The area to be searched is immediately opposite on the east side of the by-pass.


Sunday 14th December 2014 - Rushbeds Wood BBOWT Reserve (10.30am - 1pm)

Meet in the small BBOWT car-park at grid reference SP672154. This is accessed from Kingswood Road via a track across the railway, the entrance to which is about 100 metres north of the junction with the Wotton to Brill road. If the car-park is full then further space is available by the road junction.


Thursday 1st January 2015 - Otmoor RSPB Reserve (10.30am - 1pm)

Meet in the RSPB Reserve car-park (grid reference SP570127) for our traditional New Year's Day egg search. The car-park is accessed via Otmoor Lane, leading north out of Beckley.


There are likely to be further searches in the New Year but details have yet to be finalised. They will be posted on this website when available.



The Berkshire Moth Group meets every second Thursday in the month at 19:30 at Maiden Erleigh Local Nature Reserve Interpretation Centre, Instow Road, Earley, near Reading, SU 749 709 (OS175).

Contact : Grahame Hawker 01189 700144.



As with any other activity, there are hazards in the countryside and everyone taking part in a Field Meeting, Work Party or other event has a responsibility (duty of care), for their own safety and that of others. We try hard to ensure that our events present no hazards but please note and act on the following:


1.      Wear appropriate clothing and footwear. If there are unusual requirements, these are noted in the individual event details. Stout shoes are a minimum requirement.

2.      During the main summer season you may be exposed to strong sunshine for much or all of the walk. Take a hat, use sun cream or protection for exposed skin. Make sure that you have adequate food and liquid to drink with you. Equally, sunshine can easily turn to cold and rain during the day. Be prepared.

3.      Winter events may result in exposure to very cold conditions although events are cancelled in extreme conditions. Warm and waterproof clothing and footwear should always be worn. It is sensible to bring a warm drink.

4.      The leader will provide a briefing on the event before starting, with details of any known particular hazards, and will also give advice on what to do in an emergency.  Please listen carefully.

5.      At the briefing, please let the leader know if you have a mobile telephone and are willing to take it with you and/or you have First Aid qualifications.

6.      Joining the event is an indication of your interest in butterflies. By their nature butterflies do not remain conveniently by the main path and will offer many opportunities (temptations) for you to wander away.   Take particular care to look out for hazards – rabbit holes, fallen or hanging branches, barbed wire, boggy areas, etc. Beware of wet grass, particularly on sloping ground. Children are welcome at our events, but if under 16 must be accompanied by at least one adult for two children. It is the responsibility of the accompanying adult(s) to ensure that the event is within the children's ability.

7.      Dogs are normally welcome on walks but not at work parties. They must be kept under control. Any exceptions are shown in the individual event details.

8.      If you are uncertain about any details of the event, ring the leader/contact in advance. There is always a telephone number given with the event details.

9.      If you decide to leave the event early, tell the Leader.

10.   Take care at all times, but ENJOY YOURSELF.
