Host plants:
The larvae feed on rock plants like Euphorbia acanthothamnus or Antirrhinum majus (Fritsch et al. 2014).
Habitat:
Charissa subtaurica inhabits dry and hot, rocky places, garigues and similar habitats.
Life cycle:
The moths occur in two, perhaps also three generations between late March and October. Supposedly the majority (of larvae or pupae?) will enter an estivation dormancy due to summer drought. This has to be examined in the field.
Remarks:
Charissa subtaurica is known from Cyprus and Samos Island. It is possibly also found elsewhere in the East Egean. It is more widespread in Asia Minor, the Levant and the Middle East.
Hints on determination:
The males can be distinguished from the similar Ch. staudingeri by their only very shortly dentate antennae.
