Euura aquilonis
Euura aquilonis is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae feed internally in a gall formed on the leaves of dwarf willow (Salix herbacea) and polar willow (Salix polaris). Galls of E. herbaceae are similar and the larvae need to be examined to tell them apart.

Description
Descriptions of the gall differ depending on the source. According to Redfern et al. (2011) the thin-walled gall is globular, 4–10 mm diameter and usually protruding more from the underside of the leaf. The Plant Parasites of Europe website describes the gall as protruding equally on either side of the leaf. The gall is large in relation to the size of the leaf. The larvae of E. herbaceae have black spots (easiest to see in young larva) while the larvae of E. aquilonis does not.
