The Lesser Swallow Prominent (Pheosia gnoma) is a moth from the family Notodontidae.
The moth can be found across the Palearctic ecozone (North and Central Europe, Russia, East Siberia, Russian Far East, Amur) . It has a fore-wing length of 20–26 mm.
Description
The imago can be easily confused with Pheosia tremula but 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 one and two on the fore wings of gnoma.
