Food Plant: Artemisia vulgaris (Mugwort)

Egg: on the flower

Mine: August - June

Notes: The larva feeds on the seeds and makes a case from the empty seedhead (the case is the darker one on the left of the photo). The presence of the larvae can be seen by the holes they leave in the seedheads they feed on. Large Artemisia vulgaris plants growing on some waste-ground by farm buildings. Several larval cases were found here.
