Oak Nycteoline Nycteola revayana
Wingspan 20-25 mm.
A quite small species, resembling the Tortricidae in general shape and demeanour, it is often overlooked by those who don't study the 'micros'. It used to be thought to be related to that family, and was known as the 'Large Marbled Tortrix'.
It is quite variable, and the adults appear in late autumn, overwintering and appearing again in early spring.
Feeding on oak (Quercus), the species is locally scattered throughout much of Britain in deciduous woodland, but commoner in the south.
