Host plants:
The larvae feed on Linaria, Antirrhinum and related genera. I recorded larvae on Misopates orontium in Samos Island, on Kickxia (Nanorrhinum) scoparia in Gran Canaria and on Antirrhinum in Central Spain (Albarracin).
Habitat:
Calophasia platyptera inhabits dry and warm, at least semi-open habitats of all kinds.
Life cycle:
The pupa hibernates. The moths occur in two or three generations between April and September.
Remarks:
Calophasia platyptera occurs especially in Southern Europe and Asia Minor, but is found Northward occasionally up to the Southern Alps in Switzerland, South Tyrol and Austria.
