Host plants:
The larvae feed on oak, most often Quercus coccifera and perhaps also Q. ilex.
Habitat:
Catocala separata inhabits evergreen oak woodland mostly in low elevations, often near the coast.
Life cycle:
The larvae feed in April and May. The moths fly especially in June and July.
Remarks:
Catocala separata occurs in southern parts of the Balkans (Greece, S-Bulgaria, S-Macedonia, probably also S-Albania) and in Asia Minor and the Levante.
Hints on determination:
The hindwings are much darker than in the similar C. disjuncta.
