Cacopsylla brunneipennis (Edwards, 1869)

on Salix

parasite

Young larvae mainly on the female catkins and on the leaves; final stage larvae already in May. Univoltine; hibernation as adult on conifers.

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.
