(Frölich, 1828)Wingspan 11-14 mm.
This species can be distinguished from other Gypsonoma species by the creamy-white patch on the front of the head, which is pure white in G. sociana, and darker on others.
It is widely distributed over England, Wales and Ireland, though commoner in the south.
The normal flight period is July and August, when the moths fly from dusk onwards.
The larvae feed on a range of deciduous trees, windowing leaves in autumn and eating the buds, catkins, young shoots and then spun leaves in the spring.
