Host plants:
The caterpillar lives on the Swabian Alb particularly on Asplenium ruta-muraria (more than 25 larval observations on only this plant), but is according to literature generally polyphagous of herbs on the rocks.
Habitat:
Charissa pullata inhabits rocky slopes, large individual rocks and quarries.
Life cycle:
The caterpillar overwinters and can also be searched in the winter in the crevices at the base of Asplenium clusters. It is fully-grown in May. The moths fly from mid-June to August.
Endangerment: endangered
Endangerment factors:
This rock species is threatened by shadowing (rocks sink into the forest), overbuilding or degradation of the usually small-scale habitats.
Remarks:
Charissa pullata occurs in many European mountains from Northern Spain to the east. In Germany it flies in the Alps and the low mountains (Alb, Black Forest, etc.).
