Host plants:
The caterpillar lives mainly on Fraxinus excelsior, but should also use Prunus and others.
Habitat:
Lithophane semibrunnea colonizes riparian forests and other ash-rich, warm and light forests.
Life cycle:
The moth flies hibernating from late August to early May. The caterpillar lives from late April to June or early July.
Endangerment: threatened with extinction
Endangerment factors:
Lithophane semibrunnea is threatened with extinction since clear, moist texture-rich forests with a lot of ash trees decrease (the destruction of riparian forests is now almost complete, also dark forest management).
Remarks:
Lithophane semibrunnea occurs from Northwest Africa across south and Central Europe to Western Asia.
