Host plants:
The larvae feed on oaks.
Habitat:
Ennomos quercaria inhabits most often dry and hot, open oak woodlands, maquis and pastures with oaks.
Life cycle:
The egg hibernates and larvae are mature in May (sometimes not until June). The moths usually occur in a single generation from late May to early August, occasionally presumably also in a partial second generation until September.
Remarks:
Ennomos quercaria occurs from Morocco across S-Europe to Iran. In the North it is known up to Austria and Slowakia.
