Scrobipalpa halonella (Herrich-Schäffer, 1854)
The larva makes a corridor on top of the midrib; here he withdraws during feeding pauses. The inside is lined with silk and frass grains. From this main corridor irregular, often brancing, corridors enter the leaf disk. Mines mostly in the ground leaves. The larvae frequently move to another leaf, thereby making silken tubes in which frass grains are trapped. Pupation external.
Elsner ao (1999a) mention additionally Artemisia absinthium, campestris; this needs confirmation.
Larvae in July; hibernation as pupa.
