Host plants:
The caterpillar feeds on oak species (mostly shrubs).
Habitat:
Spatalia argentina colonized dry warm oak forests, especially mosaics of oak forests, young growth and dry grasslands.
Life cycle:
The moths fly in usually two generations from May to August. The caterpillars are found from June to September or early October. The pupa overwinters.
Endangerment: strongly endangered
Endangerment factors:
Spatalia argentina is threatened mainly in the north increasingly due to the declineof dry-warm, very light-oak bush forests. In southern Europe the risk is still significantly lower.
Remarks:
Spatalia argentina occurs in Central and Southern Europe. To the east, it is found to southern Russia.
