Does anybody know what butterfly this is. This was seen at Church Hill in Royston, and was very small. We thought that it was female of some sort of blue, but it doesn't match any photos on Google.
Possibly northern brown argus but Hazel, Wendy and Germain will know better than me...there are many similar looking ones
In reply to Germain:
Hazel in the Gironde estuary, France
