Wing span: 26 - 30mm

Both sexes have brown upper surfaces with white fringes. The female has faint orange lunules on the hindwing. There is a white streak on the underside.

It is widespread through much of Europe, but most common in the east and north. It is absent from the Atlantic coast, and is sporadic in the Mediterranean region.

Typical habitats are woodland clearings and margins and damp grassland with scrub, usually at low altitudes.

There is one generation between May and August, depending on locality and altitude.

The larvae feed on a range of cranesbills (Geranium spp).
