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.
The Dorset Branch of Butterfly Conservation are delighted to see that Martin Warren, recently retired Chief Executive of Butterfly Conservation, has been awarded an OBE. 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

A butterfly locked into an evolutionary struggle with its parasitic wasp nemesis, Listrodomus nycthemerusa, has bounced back this summer following a series of steep declines, results from the Big Butterfly Count have revealed! Continue reading
The Holly Blue is a butterfly which goes through a cycle of being very numerous, then plummeting to low levels, then increasing again. This is thought to be due to a parasitic wasp by the name of Listrodomus nycthemerus, which kills the butterfly in its caterpillar stage – when the butterfly numbers have been reduced far enough, the wasp has no host on which to predate, so the wasp’s numbers reduce, allowing the butterfly’s numbers to increase, and vice versa.
