Hipparchia statilinus, the tree grayling, is a butterfly of the family Nymphalidae. The species can be found in Central Europe, Southern Europe, North Africa, Anatolia and the Caucasus. This butterfly can be found in dry, rocky, grassy and bushy areas at an elevation of 0–1,400 metres (0–4,593 ft) above sea level.
Hipparchia statilinus has a wingspan of 60–68 millimetres (2.4–2.7 in). These butterflies are rather variable, especially in the shades of brown present on the wings and in the intensity of the white bands. Usually the basic color of the upperside of the wings is dull brown in the male, lighter or ocher in the female, with a fringe on the edges. Two blind or very discreetly pupillated black eyespots are present on the forewings, while the hindwings show a very small eyespot.
The underside is marbled with ocher and dusty white bands. On the underside of each forewing there are two black eyespots ringed in yellow, the upper one with a white central spot. Between... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Tree Grayling is recorded against all the insects logged in Cévennes National Park (42 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
