Description
editThe gall is a short, 1–2 millimetres (0.039–0.079 in) narrow twisted, downward roll on the leaves of purple willow (S. purpurea). It is lined with red hairs and contains mites.[1][2][3]
Similar looking galls have also been found on common osier (S. viminalis) and on sallows, which could also be A. truncatus. The mites should be identified by an expert.[1]
A. truncatus has also been known to use Salix alba as a host.[4]
