Iteomyia capreae is a gall midge which forms galls on willows ("Salix" species). It was first described by Johannes Winnertz in 1853.
Description of the gall.
The midge forms two different galls which can be found, either on the leaf bade or on a side-vein of a leaf. 
When mature the larvae drop from the gall, overwintering in the soil and pupating in the spring.
The galls are found on sallows or their hybrids and include, almond willow ("S. triandra"), common osier ("S. viminalis"), crack willow ("S. fragilis"), dark-leaved willow ("S. myrsinifolia"), eared willow ("S. aurita"), European violet willow ("S. daphnoides"), goat willow ("S. caprea"), grey willow ("S. cinerea") and "S. appendiculata".
Distribution.
The insect has been recorded in Asia, and Europe, from Ireland and Portugal in the west, through to Siberia, China and Japan in the east.
