Appearance

The moth has well-developed eye spots on the front wings and a characteristic pattern of black-brown stripes. The light-brown margins of the back wings display small triangular white spots. The robust body is also black and brown, with characteristic orange-brown stripes.

Etymology

The species is named after the botanist Nathaniel Wallich.

Behavior

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.{{cite journal |journal=Journal of Insect Physiology |volume=47 |issue=12 |year=2001 |pages=1451–1457 |author=Kotaro Konno |author2=Sachiko Okada |author3=Chikara Hirayama |name-list-style=amp |title=Selective secretion of free glycine, a neutralizer against a plant defense chemical, in the digestive juice of the privet moth larvae |doi=10.1016/S0022-1910(01)00135-4|pmid=12770151 }}

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.{{cite book |last=Carter |first=David J. |title=Vlinders (translated book) |language=nl |trans-title=Butterflies |year=1993 |publisher=Bosch & Keuning |location=Baarn |isbn=90-246-4923-4 |pages=216 |edition=First (translated) }}
