Food Plant: Artemesia vulgaris (Mugwort)

Egg: Lower surface of leaf

Mine: July, August - September

Pupa: In a cocoon, spun in detritus

Notes: Initially the mine is a long gallery underneath the leaf. As the larva feeds and spins internally the mine becomes inflated. The upper epidermis becomes mottled in appearance, turning yellow and later, purple. The larva (as shown) is at first a pale yellow-green, becoming an orange-crimson colour later.
