Gypsonoma sociana (Haworth, 1811)
white cloaked shoot
on Populus, (Salix)
In late summer the larva lives as a borer in a young shoot, of which the distal part may die off. After the hibernation the larva bores in a swelling bud; the infection then is recognisable by frass that is ejected through an opening at the base of the bud.
