Meet in the Wolfson College car park (grid reference SP514083) at the eastern end of Linton Road, Summertown, Oxford.
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 as "egg transects" 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 required! It would be useful if you could bring a hand lens (x10) or small magnifying glass. 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 has occasionally caused a search to be cancelled so if you do intend to join us please let Dave Wilton know (preferably by e-mail to firstname.lastname@example.org, otherwise tel 01296 658701 or on the day tel/text 07751 472004). Where changes are known about in sufficient time, information will also be posted on this website.
