Orgyia rupestris Rambur, 1832

Host plants:
The caterpillars live primarily on brooms as Genista corsica or Genista ephedroides.

Habitat:
Orgyia rupestris inhabits mainly broom stands in maquis and other scrub. In Sardinia, I found the caterpillar in a coastal area near Buggeru with Zygaena corsica and Coenonympha corinna in late May 2012.

Life cycle:
The egg masses usually overwinter inside the female cocoons. The caterpillars live from March to early June, more individually open at the host plant. The moths fly in June and July.

Remarks:
Orgyia rupestris is endemic to Corsica and Sardinia.
