Your Records

  • Butterfly Records
  • Butterfly Atlas Recording - An Appeal for Your Help! * New maps posted 11th July 2014 *
  • Moth Records

  • Sending in your butterfly and moth records to us is essential if we are to continue our conservation work. We welcome information on sightings from anywhere within our three counties of Berkshire, Buckinghamshire or Oxfordshire. Anyone can send in records, whether or not you are a member of Butterfly Conservation, although if you are not a member we do hope that you will seriously consider becoming one! Records must be sent to the recorders listed below for inclusion in our database, even if you have already sent some information to any of our Champions or to the Webmaster for the website Sightings Pages.

    A record can constitute any number of insects from one sighting upwards. A single Orange-tip or Hummingbird Hawk-moth seen in your garden is just as important to us as larger numbers of sightings. Records should include a minimum of date, location (preferably with a six-digit grid reference or better), species and numbers seen. Records can be sent in annually or at more regular intervals if you prefer. They can be sent by post or by e-mail. Those of you who use specialist computer wildlife recording programmes such as MapMate should contact the appropriate Recorder first to arrange a file transfer.

    Butterfly Records

    All butterfly records for Berkshire, Buckinghamshire or Oxfordshire should be sent to the Upper Thames Branch Butterfly Records Officer.

    Butterfly recording forms can be downloaded here as either Microsoft Word, Excel or Adobe PDF files. Please use the Casual Recording Form if you have records from several different locations. The Site Recording Form can be used if you have several records from just one particular site. If you have a lot of records to enter from different locations you might find it easier to use the Butterfly Records Spreadsheet:

    Completed recording forms for Garden Surveys and Churchyard Surveys should be sent to the respective Garden and Churchyard Survey Co-ordinators, as printed on the bottom of the forms. The Co-ordinators will ensure all records are passed on to the Butterfly Records Officer (see above).

    Atlas recording - can you help us fill the gaps?
    (New maps posted on 11th July 2014: All Species, Meadow Brown, Gatekeeper, Small Tortoiseshell & Common Blue)

    Our general atlas recording runs in 5-year periods; this year is the fifth and final year of the current period: 2010-14.

    The map below shows the number of species recorded in each 2km square across our area. We need your help to fill in the gaps or areas with small dots (<10 species) with new records - and we have only this year to complete this current round of recording.

    Upper Thames Branch records: 2010-14 (as at 30th June)

    1430 recorded squares - 12.9 species per 2km square (average). Note: Yellow squares are under-recorded and need further visits.

    To help you orient where these gaps are, the second map shows the major cities and towns in our area. We particularly need records from: Milton Keynes/N. Bucks, the areas around Banbury, south-east of Oxford, south of Witney, NW of Newbury and between Wallingford and Reading.

    Below we have maps of records for a few common Summer species from 2010-2014 - these show additional gaps at the species level indicating where more visits are needed.

    Any help you can give us with recording in any of these gaps will be very welcome. Please contact Jim Asher for further details. If you would like to help with recording within a particular 10km square, please contact Jan Haseler.
