Host plants:
The larva primarily feeds on Dorycnium pentaphyllum.
Habitat:
Zygaena lavandulae inhabits light, dry woods, grove rich grasslands, roadsides through forests, rocky places and similar places.
Life cycle:
The adults appear in a single generation from April to June, in the south of France mostly in May. The caterpillar seems to develop until April without real dormancy, similar to Zygaena rhadamanthus.
Endangerment factors:
Zygaena lavandulae is potentially endangered through intensive use of habitats (expansion of agriculture into formerly fallow land).
Remarks:
The moths show a strong, often darting flight that departs from the often simultaneously encountered Zygaena rhadamanthus significantly.
Zygaena lavandulae is distributed from Northwest Africa across eastern Spain and Southern France to Liguria.
