rather common species throughout Belgium. Formerly only known from the
northern part of the country, but since 1980 spread over the whole
country. Specimens of the race goossensiata are much rarer and occurs mainly in the heathlands and moorlands of the Kempen.
larva lives on a range of herbaceous plants like Senecio jacobaea,
Achillea millefolium etc. The race goossensiata (formerly
regarded as a separate species) lives on Calluna and Erica. Hibernates as pupa among plant debris.
adults fly from Late April towards mid September in one generation a
year. They are active from dusk onwards and later come to light.
