Agrotis clavis (Hufnagel, 1766)

Host plants:
The caterpillars live polyphagous on herbs and grasses at ground level.

Habitat:
Agrotis clavis inhabits gappy and often stony nutrient-poor grasslands and occasionally also dry ruderal areas.

Life cycle:
The caterpillar overwinters. In spring, it usually hides under stones or superficially digged in the soil. I found the larva in South Tyrol in the vicinity of the Passo di Resia (Reschen) in 1900m asl at a grown dry embankment wall between sparse pastures. The moth fly especially from June to early August.

Endangerment: endangered

Endangerment factors:
Agrotis clavis is endangered, because nutrient-poor grasslands today only have a small fraction of their former range and continue to decline.

Remarks:
Agrotis clavis occurs in large parts of Europe and temperate Asia to Korea.
