Euura pedunculi is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larva feed within galls on the leaves of sallows (Salix species). It was first described by Theodor Hartig in 1837.

Description of the gall

The gall is found on the underside of a leaf of the host pant, is gobular or ovoid and up to 5 mm. It can be green or yellow, somtimes flushed wth a red, can have warts and varying density of hairs. On the upperside of the leaf is a yellowish scar which can be flush with the surface or very slightly raised.[2][3]

The gall is found on eared willow (S. aurita), goat willow (S. caprea), the hybrid of goat and tea-leaved willow (S. caprea x phylicifolia), grey willow (S. cinerea), S. silesiaca and S. starkeana.[3][4]

Distribution

This species is found in most of Europe north to Inari, Finland and east to Sakhalin, Russia.[1] The gall is common in Great Britain and Ireland.[3]
