Host plants:
The larvae are polyphagous on small trees, bushes and herbs, often Rubus.
Habitat:
Lasiocampa grandis inhabits sunny, bushy sites such as open woodlands, maquis, garigues and similar places.
Life cycle:
The moths occur in early autumn. The eggs are dispersed in the habitat and fall to the ground. The Larvae hatch in autumn and develop until next May. The pupa estivates in its cocoon.
Remarks:
Lasiocampa grandis occurs in SE-Europe (southern part of Balkan Peninsula) and in SW-Asia (e.g. Turkey and Near East).
Hints on determination:
The larvae are easily separated from the sometimes syntopical and synchroneous larvae of L. terreni by the absence of large black spots on the neck and anal shield.
