Rabdophaga triandraperda Barnes, 1935

on Salix

gall

Under the bark of twigs live a number of orange or red larvae, each in a gall chamber for its own; the branches are not or only weakly swollen. Before they pupate, the larvae make emergence openings. These “shot holes” are the clearest indication of their presence. Galls mainly in the basal part of the current year’s shoots. Probably multivoltine.
