Description of the gall

These are simple galls with the leaf rolled downwards affecting only one side of the leaf. The female forms the gall before she lays her eggs, with the caterpillar feeding inside the fold. It will also feed on ungalled parts of the leaf, or other leaves.[2] In Great Britain the gall is found on white willow (Salix alba) and crack willow (S. fragilis). Elsewhere it has been found on weeping willow (S. babylonica) and almond willow (S. triandra).[3]

Redfern et al. state that, in Great Britain, it is safe to identify the galls of this species and Euura destricta by the foodplants. E. destricta feeds on bay willow (S. pentandra). In Great Britain, other Euura species do not form galls on these host plants.[2]

Distribution

The sawfly has been found in Great Britain (England and Wales) and the Netherlands.[2][3]
