case

Greyish black tubular composite leaf case of about 5-6 mm. The case is composed of numerous rings, each cut out of the lower epidermis of the hostplant. The rear end is strongly curved, like the handle of a walking stick. Mouth angle 45°. The larva pupates in its case at the upperside of the leaf.

The development of the larva takes two years, with a diapause in early summer, when the plant develops new foliage. In the first year the cases consists only of the strongly curved part of the complete case.
