Black Hairstreak, Bedford Purlieus

Found this at Bedford Purlieus this afternoon. I've only ever seen them at Glapthorn Cow Pastures before now. It's had a hard time of it and seems quite early in the season.

Other insects about were Large Skippers, loads of Speckled Woods, a Red Admiral, Southern Hawkers, a teneral Common Darter and a fair few Common Blue Damselflies. Green Oak Tortrixes were flitting around the oak trees and the grass moths Crambus lathoniellus and Chrysoteuchia culmella were in the grassy areas.
