Aculus truncatus is a species of mite which causes galls on the leaves of purple willow (Salix purpurea). It was first described by Alfred Nalepa in 1892.

Description

The gall is a short, 1–2 mm narrow twisted, downward roll on the leaves of purple willow (S. purpurea). It is lined with red hairs and contains mites.[1][2]

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]
