Coleophora albicosta (Haworth, 1828)
Ulex europaeus, Belgium, prov. Namur, Maizeret © Jean-Yves Baugnée
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, boat-shaped 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.
Ulex europaeus, gallii.
Larvae from mid-August. The hibernation case is made in November.
