Large Blue on Bramble - Sarah Meredith 29th June 2010

Evening all,

The weather today was mixed but mainly sunny and warm, cloud was moving fast across the sky so at intervals the sun was obscured. The Large Blue’s were flying as soon as I arrived on site, it was cooler with a stronger breeze this morning but still warm enough to keep the Large Blue’s from perching for any length of time.

Today I was learning how to carry out egg counts on site to gain a full understanding of the population size on site. This involves sitting on a huge number of prickly things such as Thistle, Spiny Restharrow, Gorse and anything else resembling a sharp object!! Due to working on slopes it also involves sliding down once you have actually sat down before coming to a resting point!!! Once all of that happens it is time to actually check the Thyme flower heads for eggs and record the number of eggs to Thyme plants.

It will be interesting over the coming week to see how many eggs we count and the final total. Large Blue numbers are starting to decline but there are still a good number on site, they could be found flying around the scrub areas this afternoon flying around the long grass areas and then out up the slopes and around. We are watching with interest how numbers will decline over the next few days, due to the long time it has taken to reach peak it could be that numbers decline sharply rather than gradually as has been the case over the past few years. But only time will tell, tomorrow I will be spending more time looking up and at the Large Blue adults rather than into Thyme flower heads so it will interesting to see what is happening over the whole site.

If you are visiting over the next few days I am sure you will get sightings of the Large Blue and if there is cloud around with breaks of sun then you might be in luck and get the perfect open wing shot!!

About largebluewarden

I am the Large Blue warden for Collard Hill, and will be on site Wednesday through to Sunday with other volunteers. I graduated in December 2009 from Reading University, with an MSc in Wildlife Management and Conservation. Before coming to Glastonbury to work with the Large Blue, I was carrying out research into the Glanville Fritillary on the Isle of Wight. While my thesis for my Msc was looking at ‘The habitat requirements of the Small Heath Coenonympha pamphilus in the uplands’. Butterflies and photography are my passion and I am looking forward to a great flight season on Collard Hill and hope to meet many of you who are reading this blog.
