The Spectacle Abrostola tripartita
Wingspan 27-30 mm.
This moth derives its English name from the raised tufts of scales on the thorax, which resembles a pair of spectacles when viewed from the front.
It is a fairly common species throughout Britain, and is a regular visitor to light. It has one or two generations, flying between May and September.
The larvae feed on nettle (Urtica dioica) and the species passes the winter as a pupa.
