The larvae feed on Verbascum (including Verbascum lychnitis, Verbascum nigrum and Verbascum austriacum) and Celsia species.

The larvae feed on Verbascum species (including Verbascum lychnites, Verbascum thapsus and Verbascum nigrum), Scrophularia canina and possibly Astragalus ponticus.

Verbascum nigrum L. (Dark Mullein) is a species of biennial or short-lived perennial herbaceous plants in the genus Verbascum (mullein), native to dry open sites in Europe and the Mediterranean region.
