Brown Hairstreak (Thecla betulae)
A rare species nationally but fairly widespread in well-hedged farmland east and west of Taunton. Even so, Brown Hairstreaks are hard to see as the males, which are a fairly uniform brown on the upperwing, remain in the tree tops and though the females, which have a striking orange patch on the forewing, do visit nectar plants their main object is to lay their eggs on blackthorn bushes, usually within a yard of the ground, a secretive operation easily missed.
