Adscita geryon (Hübner, 1813)

Host plants:
Helianthemum nummularium and other species of Helianthemum. In rearing the larvae also accept Geranium.

Habitat:
Adscita geryon colonizes limestone grasslands and Alpine meadows and pastures up to 2300m above sea level.

Life cycle:
After hibernation the caterpillars are fully-grown between late April and mid-May. The moths fly from late June to mid-August.

Endangerment: endangered

Endangerment factors:
Due to loss and improper maintenance of the habitats (overgrazing, pens, but also abandonment and following succession) Adscita geryon is endangered outside the Alps in central Europe.

Remarks:
Adscita geryon is widespread in Europe, but is missing in the very north and south. Outside Europe, it is known only from northern Turkey.
