Scalloped Hazel

The Scalloped Hazel (Odontopera bidentata) is a moth of the family Geometridae. It is a common species of northern and central Europe including the British Isles.

This is a very variable species with the wing colour ranging from whiteish through buff and brown to black, sometimes with variegation, but it is always easily identifiable by the white discal spot on each wing and the characteristic "ragged" margin of the wings. The wingspan is 46-50 mm. The adults fly at night in May and June and are attracted to light.

The larva is green or brown and very twig-like and feeds on a variety of trees and shrubs. It has been recorded on birch, hawthorn, larch, pine, privet and oak. The species overwinters as a pupa.
