Food Plant: Artemisia maritima (Sea Wormwood)

Mine: August - June

Notes: The larva starts in August to mine the leaves and then later feeds on flowers and seeds. The case is trivalved and has longitudinal stripes (as shown). It then leaves the food plant, when fully fed in September, and attaches its case low down on a stem. It can be found on the edges of salt marshes on the East coast.
