Host plants:
The larva feeds on mosses, algae, lichens, old grasses, litte and flowers, etc.

Habitat:
Eilema cereola inhabits alpine, usually slightly matted pastures and meadows especially in the (southern) central Alps, that are sometimes interspersed with stones and sometimes located in open forest between mostly 1400 and 2200m above sea level.

Life cycle:
The caterpillar overwinters half-grown. I found them in early June in the Valais in a gravel interspersed gully in very sparse mountain forest at 2000 meters above sea level in the search for Lycaena larvae under Rumex scutatus. The moth flies from late June to mid-August.

Endangerment factors:
In places, Eilema cereola can be endangered by skiing infrastructure, chalet construction, too intense grazing or avalanche barriers.

Remarks:
Eilema cereola represents morphological characteristics between Eilema and Setina. Because of that some authors treat Eilema cereola in the specially created genus Setema. In my opinion, it is much closer to Eilema.

Eilema cereola occurs from Scandinavia and the Baltic countries eastwards (Russia). A disjunct occurrence is known from the Alps.
