Coenonympha glycerion, the chestnut heath, is a butterfly species belonging to the family Nymphalidae.

It can be found in Eastern Europe and east across the Palearctic to Siberia and the Caucasus to North Korea.

The disc of the forewing of the male on the upperside is washed with copper-brown, while that of the female is yellowish brown.

The underside of forewing entirely without ocelli, rarely with a small, pale, apical ocellus.

Beyond the middle are 2 large irregular white sinuous patches, either separate or thinly connected, by which the nymotypical form is recognized at a glance.

(48 c), on the other hand, the ocelli of the hindwing are very regular and distinct and appear on the upperside in the shape of brownish rings, resembling hero from Central Asia.

The butterflies are on the wing in June and July, typically found on grassy roads in woods and in damp meadows.
