Host plants:
The larvae feed on Fabaceae, obviously most often Hippocrepis species. I recorded them in Cyprus on Hippocrepis unisiliquosa.
Habitat:
Autophila dilucida inhabits dry and warm places like rocky slopes, mountains, nutrient-poor grasslands, garigues etc.
Life cycle:
The moth hibernates e.g. in entrances of caves. They can be found between June or July and April. I recorded mature larvae (often under stones during daytime) in Cyprus already in mid-April 2017. Further North and in the mountains the larvae may still feed in June or even July.
Remarks:
Autophila dilucida occurs in large parts of Southern Europe and in Asia Minor. In the North ist is found up to S-Switzerland, S-Austria and parts of E-Europe.
