The oak hook-tip (Watsonalla binaria) is a moth of the family Drepanidae.

It is quite common in England and Wales, but not found in Scotland and only recently in Ireland.

Usually two broods are produced each year, the adults flying in May and June and again in August [1].

Two black twin points on the front wings are the clearest differentiator.

The larva is brown with yellow markings and shows the typical drepanid shape with a tapered tail.
