Host plants:
The larvae are polyphagous on most often low-growing shrubs, trees and occasionally also herbs. They often feed on broom species.
Habitat:
Orgyia trigotephras inhabits dry and warm areas like garrigues, maquis or scrub.
Life cycle:
Orgyia trigotephras occurs in one or - if summer drought does not prevent it - also several generations between May and autumn. I found the larvae in Cyprus in April. The egg hibernates.
Remarks:
Orgyia trigotephras occurs in N-Africa, S-Europe and W-Asia.
