Drasteria cailino (Lefèbvre, 1827)

Host plants:
The caterpillar lives on various willows (Salix, often Salix purpurea).

Habitat:
Drasteria cailino inhabits dry and warm, but locally more humid, rocky habitats such as gravelly river valleys, rocky slopes, gravel plains, etc. I met larvae in Northern Greece and Spain at very sparsely vegetated, stony embankments and road sides with small bushes of Salix purpurea.

Life cycle:
The moths fly from May to July and obviously in a second generation between July/August and September. They prefer to rest on the ground and among the stones.

Endangerment factors:
Drasteria cailino may be at least locally endangered according to the habitat selection.

Remarks:
Drasteria cailino occurs from Southern Europe to Central Asia. In southern Europe sites are known from the central and southern Iberian Peninsula and Southern France, locally from Italy and from the southern Balkans to the Crimea and southern Russia.
