Hipparchia fagi, the woodland grayling, is a butterfly of the family Nymphalidae.

Etymology

The Latin species name fagi, meaning of "beech" (=fagus), refers to the prevailing species of trees in the relating biotope.

Subspecies

There are tree subspecies:

• Hipparchia fagi fagi Scopoli, 1763
• Hipparchia fagi sicula (Schwingenschuss, 1942)
• Hipparchia fagi tigridia Agenjo, 1969

Distribution and habitat

This species is widespread in southern half of Europe, from south of Belgium to central Germany, southern Poland, and to western Siberia (Yekaterinburg region east of the Urals). It occurs on broad-leaved deciduous forests, coniferous woodland, grassy vegetation, in woodland glades and woodland rides from sea level to 1,500 m–2,000 m elevation.

Description

Hipparchia fagi has a wingspan of 66–76 mm (2.6–3.0 in). These large butterflies have dark brown uppersides of the wings, with a fringed margin, a white submarginal band more evident in the females and one black eyelet at the apex of each forewings. In the males the white band has a single very small eyelet on each hindwing, sometimes showing a white pupil, while in the females it shows one or two ocelli.

The underside of the forewings is rather similar to the upperside: The hindwings are marbled of brown and white with a broad white band. The white band on the internal edge of the underside hindwings is curved, while the white band on the underside forewings is often without a significant indent.

The colouration and pattern of these butterflies are an excellent camouflage on the bark of the trunks where the butterfly usually rests, with the eyespots hidden by the closed wings. It is rather similar to Hipparchia alcyone, Hipparchia syriaca and Hipparchia genava.

The caterpillar has a pale brown head with four darker streaks. Body is light brown with a bifid posterior end, a dark brown dorsal band and brownish lateral bands.
