Habitat:Idaea aureolaria has high requirements and only inhabits particularly hot-dry habitats such as steppe slopes, full dry grasslands, rocky slopes and other sheltered grasslands. In Valais, I found the moths commonly at the foot of a steppe slope at a wayside exclusively in higher vegetation. In the surrounding, low growing to rocky structure no moths were seen.
Endangerment factors:Idaea aureolaria is endangered north of the Alps by habitat loss. Some of the habitats fell fell victim to vineyards, while others were built over or overgrew after abandonment of extensive grazing. 041b061a72
