Dewick's Plusia Macdunnoughia confusa
Wingspan 32-38 mm.
This moth is a vagrant to Britain, having occurred only a few dozen times, mostly attracted to light on the south and east coasts. August is the optimum month for this species, but records have occurred between July and October.
On the continent it is double-brooded, and the larvae feed on a range of plants, most commonly nettle (Urtica dioica).
