Oak Hook-tip Watsonalla binaria
Wingspan 18-30 mm.
The 'hook-tip' moths get their name from the shape of the tips of the forewings, and this species is one of the smaller members of the group.
Occurring in oak woodland and parkland, it is reasonably common in the southern half of Britain.
It is double-brooded, flying in May and June, and again in August. Mainly nocturnal in habits, it can be attracted to light.
As may be expected, oak (Quercus) is the larval foodplant.
