Craspedolepta subpunctata (Foerster, 1848)

on Chamerion

gall

the eggs are randomly deposited at the underside of the leaves; the young larvae drop to the ground and start feeding on the roots. Here a gall develops, consisting of a tangle of bleached, strongly branched, spiralled and swollen roots; the gall is about a cm in diameter. Only after hibernation the pale ochreous larvae of the final, 5th, instar migrate upwards, and live, without causing any galling on the leaves.
