The moth can be found in selected parts of Eurasia. It has a forward wing length of 20–26 mm. The moth survives winter as a pupa underground.
The imago can be easily mistaken with Swallow Prominent (Pheosia tremula). Except the latter is bigger and the white figure at the back of the forward wing is smaller with Pheosia tremula.The host plant of the Lesser Swallow Prominent is the birch.
