Orange Underwing
Archiearis parthenias
GeometridaeABH 70.203 B&F 1661Very local, but under-recorded, both as a day-flier and because the adults fly very early in the year. Associated with birches, the largest populations seem to be around Shapwick and Ham Wall. Surprisingly few records from the Blackdowns and Exmoor.
