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''.
