Erebia rondoui Oberthür, 1908

Host plants:
The larva feeds on grasses (probably especially Festuca).

Habitat:
Erebia rondoui inhabits more dry and partly stony, gappy pastures and rocky slopes between 1600 and 2500m asl.

Life cycle:
The adults mostly occur between July and early or mid-September. But in mid-October 2013 I observed at least three quite fresh females in the French Canigou massif in 2000m asl which are most likely extreme stragglers. The larva hibernates.

Remarks:
Erebia rondoui is endemic to the Pyrenees. But in the south Spanish Sierra Nevada a similar species (Erebia hispanica) occurs. Erebia rondoui is often considered a subspecies of the latter.
