Description

The bud of the host species is about twice the normal size and pear-shape. The greenish larva feeds within the gall which also contains frass and the bud falls to the ground in the autumn where the larva pupates.[2] Several buds on the same shoot can be galled and the insect has a single generation per year (i.e. univoltine).[3] Most species of Euura are monophagous on Salix species but there is some discussion on whether Euura mucronata is a group of closely related species, each feeding on different Salix species, or whether it is polyphagous feeding on over thirty species of willow.[2][4]

Distribution

Euura mucronata is found in Europe from Ireland, east to the Ukraine and from Norway, south to Portugal.[5]
