459 Ypsolopha sylvella
(Linnaeus, 1767)
Wingspan 18-20 mm.This oak-feeding species is locally distributed in much of England north to Yorkshire.
It closely resembles the slightly commoner Y. alpella, which also is found in oak woods, and has a similar distribution, so care has to be taken with identification.
The adult moths occur during August and September, and can be attracted by light.
