Host plants:
The larvae feed on dwarf shrubs like Calluna and brooms.
Habitat:
Orgyia aurolimbata inhabits heathland and slopes with brooms, pastures rich in dwarf shrubs and similar sites up to at least 2100m.
Life cycle:
The larvae develop between April and July/early August (according to altitude). I recorded still half-grown larvae in 2000m asl in the French east Pyrenees in late July 2013 and fully-grown larvae in the Spanish Sierra de Gredos between 1000 and 2000m in late June 2025. The larvae mostly lived on Genista bushes up to 2 metres height. The moths are on the wing especially between June and early September.
Remarks:
Orgyia aurolimbata occurs locally especially in the mountains of the north and west of the Iberian Peninsula and just reaches the French eastern Pyrenees.
