Craspedolepta nebulosa

Craspedolepta nebulosa (Zetterstedt, 1828)

on Chamerion


Around June the female deposits a row of eggs at the underside of a very young leaf along the midrib. With the growth of the leaf the row of eggs is shifted outwards, while the leaf margin curls over the eggs and young larvae. (Occasionally the eggs are deposited at the upperside of the leaf, and the leaf margin accordingly curls upward). Even before the first moult the larvae leave their gall and drop to the ground. They then suck at the roots, that start to proliferate and ultimately form a globular mass like the root galls of C. subpunctata. After the hibernation black 4th instar larvae migrate up the plant, moult on the plant to pale ochraceous 5th instar larvae that for one or two weeks live at the underside of the leaves, then become adult and oviposit (Lauterer, 1993a).
