Pheosia gnoma, the lesser swallow prominent, is a moth from the family Notodontidae. The species was first described by Johan Christian Fabricius in 1777.
The moth can be found across the Palearctic realm (northern and central Europe, Russia, eastern Siberia, Russian Far East, Amur). It has a forewing length of 20–26 mm.
Description
The imago can be easily confused with Pheosia tremula but P. gnoma is usually smaller, and the ground colour has usually less brown in it. The chief character by which it may be distinguished is the broader and clearer white wedge-shaped mark between veins 1 and 2 on the forewings of P. gnoma.
