Rabdophaga triandraperda Barnes, 1935
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.
Salicaceae, narrowly monophagous
According to Roskam also S. viminalis, but see R. viminalis.
