Coleophora albicosta: case on Ulex europaea

another specimen

parasite

After a larva has eaten out its first pod it makes a case of out of a section of a calyx. This gall is ± 7 mm long, trivalved, with a mouth angle of 45°-60°. Once full fed it leaves the first case and makes a new silken case in the angle between the lower, boatshaped part of the calyx and the keel of the flower; the flower dries, but doesn’t fall off. In the new case it hibernates, and pupates in the spring.

hostplants
