case

Larva in a spatulate leaf case, at the underside of the leaf. The case is 10-12 mm long, straight, brown, tubular, laterally compressed, patently hairy (depending on the host plant), bivalved. The mouth angle is rather variable, usually around 45°. A peculiar character of this species is that after each moult the larva makes a new case; the old, vacated case is left at the place where the new one is made, at the leaf margin.

hostplants

Asteracee, oligophagous

Eupatorium cannabinum; Inula conyzae, oculus-christi, salicina; Pulicaria dysenterica.

On Crete larvae have been found on Ruta (Baldizzone, 1990b); for the moment this seems xenophagy.

phenology

The larva is fullgrown in end May, early June (Emmet ao, 1996a).
