Host plants:
The larvae feed on Chondrilla juncea, according to literature occasionally also on related Asteraceae.
Habitat:
Schinia cognata inhabits dry and warm places with the host plants such as steppes, sandy grasslands, fallow land, dry slopes etc.
Life cycle:
The pupa hibernates. The moths usually occur between late June and mid-August and fly during daytime. The larvae are found especially on flowers and fruits of their host plant between late July and September. I could beat them from Chondrilla in Bulgaria at the foot of volcanic hills near Rupite in early August 2017.
Remarks:
Schinia cognata occurs from E-Austria and Slovakia Southeastwards in Europe to Greece and S-Russia. Additionally there is a small and very restricted population in SE-France (Durance valley in Hautes-Alpes).
