Coenonympha glycerion, the chestnut heath, is a butterfly species belonging to the family Nymphalidae. It is also known as Coenonympha iphis. It can be found in Eastern Europe and east across the Palearctic to Siberia and the Caucasus to North Korea.
C. glycerion is a small orange-brown butterfly, similar in size to a small heath but with distinct eye-spots (ocelli) on its hindwing. The hindwing has several ocelli on the underside, often five or six. Beyond the middle are two large irregular white sinuous patches, either separate or thinly connected. The underside of the forewing is meanwhile either entirely without ocelli, or has a small, pale, ocellus near the tip of the wing.
There is some variation between sexes: the disc of the forewing of the male on the upperside is washed with copper-brown, while that of the female is yellowish brown, in varying shades. The hindwing is uniformly blackish brown.
The Larva is dull green with a blue-green head, a dark dorsal stripe, a pale lateral one, as well as a red anal fork; the spiracles yellowish red. The pupa is green with white-spotted abdomen and dark-edged wing-cases. Ssp. anaxagoras - Central & Eastern... Wikipedia →

Possible
About 30% of wildlife watchers report a Coenonympha iphis sighting in Mercantour National Park on a given day, based on 49 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 39th most-seen of the 412 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Coenonympha iphis in Mercantour National Park on a given day, against under 5% in January–May and September–November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Coenonympha iphis sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 10 parks where we can rate Coenonympha iphis sightings, Mercantour National Park has the highest daily chance: about 30%. Next come Biebrza National Park (Poland, about 20%) and Kiskunság National Park (Hungary, about 20%).

GBIF citizen-science records
It is estimated from how often the Coenonympha iphis is recorded against all the insects logged in Mercantour National Park (49 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.
