The larvae feed on Fraxinus excelsior, Ligustrum and common lilac.
In captivity they also feed on elderberry.
They are able to neutralize plant toxins produced by Ligustrum.

The moths are active at night; during the daytime, they rest with outspread wings on tree trunks or on the ground.
When disturbed, the moth does not fly away, but fiercely shakes.
