Host plants:
The caterpillar lives on Dorycnium pentaphyllum, according to literature also on Lotus.
Habitat:
Zygaena occitanica inhabits the maquis, garrigues, scrub, dry grasslands, mountain slopes, dry river gorges, very sparse forests and bushland with the most important host plant Dorycnium.
Life cycle:
The larvae are easy to shake off the Dorycnium bushes. I found them this way in Provence in late April and May. The moths fly in July/August.
Remarks:
Zygaena occitanica occurs in Atlanto-Mediterranean dissemination from Andalusia across the Iberian Peninsula and Southern France to Liguria.
