Orthosia rorida (Frivaldszky, 1835)

Host plants:
The species is allegedly polyphagous on deciduous wood. I tapped many larvae exclusively from Paliurus spina-christi (Rhamnaceae) in Northern Greece.

Habitat:
Orthosia rorida colonizes dry, hot and shrub-rich habitats. I found them on a very xerothermic slope with Proterebia afra and Pyrgus sidae.

Life cycle:
The moths overwinter almost developed in the pupa and fly mainly in March and April. The caterpillar lives from mid-April to late May or early June.

Remarks:
In Europe, Orthosia rorida is limited to the south (whole Mediterranean, sporadically to the southern foothills of the Alps). It is quite common for example in Northern Greece. Additionally it is found from Asia Minor and the Near East to Iran.
