Aceria iteina
Aceria iteina is a species of mite which causes galls on the leaves of sallows and their hybrids. It was first described by Alfred Nalepa in 1925.
Description of the gall
The gall is a green or reddish, toadstool shaped pouch, 2–4 mm high with a narrow neck, protruding on the upper-side of a leaf. On the underside the gall also protrudes and there are mites and hairs inside a narrow slit. The gall has been found on eared willow, goat willow, grey willow and their hybrids.;Similar species
Identification of mite galls on Salix species is tentative and need to be verified by an expert. It is possible that A. iteina is one of a number of closely related species with A. salicis on ''S. caprea''
