Bactericera curvatinervis (Förster, 1848)

on Salix

gall

The number of Psylloidea living, mostly monophagously, on Salix is considerable. Probably the effect of the infestation will not differ much from one species to the other: small hypophyllous pits, each one housing a flattened larva, and, under more heavy infestation, curling, especially of the younger leaves.

On Salix two genera occur, belonging to dfferent families: Bactericera (Triozidae) and Cacopsylla (Psyllidae). In Triozidae larvae the wing rudiment anteriorly has a lobe that extends as far as the front of the head; in Psyllidae this lobe is missing.
