Host plants:
The caterpillar lives polyphagous on deciduous trees, shrubs, vines and perhaps herbs. Dead or wilted leaves are preferred. The caterpillar was found on several occasions in the leaf litter. I tapped larvae from Clematis vitalba tendrils with many dead leaves around one to two meters above the ground in September 2010. In breeding, the caterpillars accepted easily living leaves of Rubus fruticosus and Clematis vitalba.
Habitat:
Herminia tarsipennalis inhabits habitats of all kinds which are rich in deciduous wood. It is most common in open woodlands and on the edges.
Life cycle:
The adults fly depending on the location in one or two generations from May to September (in case of a single generation usually between late June and early August). They can be flushed easily. The caterpillar overwinters in last instar and feeds in the spring for about two weeks (depending on temperature even longer).
Remarks:
Herminia tarsipennalis occurs in Europe (not in Central and Northern Scandinavia) and in temperate Asia to the Pacific.
