Host plants:
The larvae feed on bushes and deciduous trees like oak or Lonicera, but prefer very often Ligustrum or Fraxinus.
Habitat:
Trichopteryx polycommata inhabits riparian forests, bushy slopes and other grove-rich, sunny to semi-shady habitats.
Life cycle:
The moths occur between mid or late February and late April. The larvae develop from late April to June. I found it several times in a riparian woodland near Memmingen (S-Germany) when searching for larvae of Amphipyra perflua. The quite developed moth hibernates in the pupal skin.
Endangerment factors:
Also this species is more and more displaced by modern dark forest management.
Remarks:
Trichopteryx polycommata occurs in large parts of Europe and temperate Asia to Japan.
