Host plants:
The larvae feed on flowers of Chondrilla and Lactuca.
Habitat:
Haemerosia renalis inhabits dry and warm open woodland with rocky clearings, stony or rocky embankments, road side verges and other sites with open soil and the host plants.
Life cycle:
The pupa hibernates. The moths occur most probably in two overlapping generations between June and early September. The second generation should be incomplete. The larvae occur between July and late September most often in small groups openly in the inflorescence.
Remarks:
Haemerosia renalis occurs only locally in parts of S-Europe (S-France, Central Italy, Balkans) and across Asia Minor to Central Asia.
