Nationally scarce (Nb) along woodland edges and rides, and in parks and gardens throughout much of south-eastern England. In Hampshire virtually restricted to Portsea Island, with a few isolated records elsewhere in the county and on the Isle of Wight. Wingspan 12-15 mm. Readily recognised by its distinctive forewing coloration and markings, somewhat reminiscent of
Cherry Bark Moth Enarmonia formosana, but
G. minutana is smaller and has paler forewing coloration and lacks the white interspaces between the costal strigulae, while the hindwing is paler and has greyish instead of white cilia [Bradley]. Larva feeds on Black Poplar, White Poplar and Aspen, living between leaves spun together with silk.
