Biology

Adults are on wing from May to July. There is one generation per year.

The larvae feed on the flowers and leaves of Solidago virgaurea, Solidago canadensis, Artemisia absinthium and Artemisia vulgaris hiding by day under the leaves close to the ground. The species overwinters in the pupal stage, in a tough earthen cocoon usually among surface debris or sometimes underground.
