We hold an annual training course in butterfly identification, which particularly looks at the can-be-hard-to-tell apart families, like the whites or the blues. This year’s took place on 27 May in Cerne Abbas and was, as usual, a sell-out, with 23 people attending.
The day, run by volunteers of the Dorset Branch of Butterfly Conservation, looks not just at identification, but also how to survey and record butterflies.
In the morning, attendees learnt the techniques of butterfly identification. In the afternoon, when the sun fortunately came out, they went out to practice their new knowledge in the butterfly-rich location of the Cerne Giant. There was great excitement when, as well as adult butterflies of various species, a Marsh Fritillary chysalis was spotted.
Our thanks to James Gould (who said he enjoyed the day, especially the cakes!) for the following photos.

In order to help butterflies, we need to know about them first. If you haven’t spotted our Distribution Atlas pages yet, do go and have a look at them; they can be accessed via our ‘Recording‘ page.
Our Records Officer, Bill Shreeves, has done a magnificent job taking both a long-term and short-term view of our records from 1970 to 2014, showing how the various species have fared in Dorset. Each species has a distribution map of sightings between 2010 and 2014, followed by information showing population trends.
This is still a work in progress. We will be adding Dorset flight-time charts soon, and Bill is working on further ways of illustrating trends, and hopefully we may be able to crunch the numbers to achieve some abundance data, too.

Some people think this stands for ‘Officer of the Most Excellent Order of the British Empire‘; we think it’s for ‘Outstanding Butterfly Expert’! Continue reading
