Hydriomena furcata (Thunberg, 1784)

Host plants:
The caterpillar lives on Vaccinium and Salix, but also other wodds such as Corylus. I found caterpillars in northern Ticino and the Black Forest on Vaccinium myrtillus and in the Swabian Jura on Salix caprea. In the French Alps, I observed larvae on Salix in great abundance still in early July 2012 in 2300m asl.

Habitat:
Hydriomena furcata colonizes blueberry-rich forests and those with a lot of soft wood. It also occurs in alpine pastures with single willows.

Life cycle:
The egg repectively the caterpillar within the egg ehell overwinters and the larva is mature in May. She lives in a housing made of spun leaves. The moths fly from mid-June to August.

Remarks:
Hydriomena furcata is widespread Holarctic. The moths are very variable.
