Coenonympha glycerion (Borkhausen, 1788)

Host plants:
The larva feeds on like Bromus erectus or Festuca ovina.

Habitat:
Coenonympha glycerion colonizes juniper heathland, limestone grasslands, dry and nutrient-poor clearings in floodplain woodlands and alternating dry and wet fen meadows etc. This species can cope with different conditions in calcareous grasslands, including grazing, mowing in autumn andlonger fallow periods.

Life cycle:
Coenonympha glycerion hibernates as a caterpillar. This is observed occasionally during the day on blades of grass close to the ground from April to early/mid-June. The adults usually fly from June to early August in a single generation In Eastern Central Europe (also elsewhere?) a second generation in late summer/early autumn is observed.

Endangerment: endangered

Endangerment factors:
The threat situation is uneven depending on the condition and share of the extensive, rather dry grasslands in the landscape. In the Swabian Jura Coenonympha glycerion is still common in almost all limestone grasslands. In the foothills of the Alps, however, there is a strong decline. In the Iller valley for example it is known only in very low numbers from one final site near Memmingen.

Remarks:
The distribution stretches from Europe to Asia (Mongolia).
