Here I observed larvae in May (July 2006). [N]

Host plants:
The larvae mostly feed on Quercus species, besides also on other deciduous woods.

Habitat:
Orthosia cruda inhabits oak-rich forests, parks, and other woody locations.

Life cycle:
The adults overwinter in the pupal skin and emerge in March or April. The caterpillars occur in a brown and a green version. I tapped them in May and June from oaks.

Endangerment factors:
Orthosia cruda is widespread, but loses many habitats due to the decline of oaks in Central Europe.

Remarks:
Orthosia cruda is distributed from the Iberian Peninsula to West Asia.
