Description

Wing span: 40 - 46 mm

This butterfly has velvety black upper surfaces, with one white band on the forewings and two on the hindwings. The sexes are similar.

It is rather widespread in SE Europe, but local and never abundant.

It is found in damp deciduous woodland, forest roads and clearings, and river valleys between 200 and 1500m.

There are two broods per year, the first in May/June and the second in July/September.

The main larval foodplants are Spring Vetchling (Lathyrus vernus) and Black Bitter Vetch (L. niger).

Adults have a characteristic gliding flight.
