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 →

Rare
Under 5% of wildlife watchers report a Tree Grayling sighting in Pyrénées National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 657th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Tree Grayling in Pyrénées National Park on a given day, against under 5% in October to July, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Tree Grayling sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 parks where we can rate Tree Grayling sightings, Pyrénées National Park ranks 5th at under 5%. The best odds are in Kiskunság National Park (Hungary, about 20%), Sierra Nevada National Park (Spain, about 20%) and Sierra de Guadarrama National Park (Spain, about 10%).
GBIF citizen-science records
It is estimated from how often the Tree Grayling is recorded against all the insects logged in Pyrénées National Park (17 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.
