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.

The host plant of the Lesser Swallow Prominent is the birch- Betula (British Isles), Betula pendula (Finland) Betula pubescens (Finland).[1]

The moth survives winter as a pupa underground.
