(Brischke, 1883)

Euura venusta is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae feed within the leaf-stalk (or petiole) of willows (Salix species) forming a gall. The sawfly was first described by Carl Gustav Alexander Brischke in 1883.

Description of the gall

The gall is formed in the petiole and is 8–10 mm long and 2–4 mm wide at the base. It contains one larva, along with its frass, and can be found on eared willow (S. aurita), goat willow (S. caprea), grey willow (S. cinerea), downy willow (S. lapponum) and S. silesiaca. [1] [2]

Euura venusta is one of three closely related species known as the Euura amerinae species subgroup. The other member of the group is E. testaceipes (Brischke, 1883). [3]

Distribution

The sawfly has been found in central and northern Europe and the Russian far east, including Armenia, Belgium, Great Britain, Luxembourg, Norway, Russia and Sweden. [1] [2]

<i>Euura</i> Genus of sawflies

Euura is a genus of sawflies of the family Tenthredinidae, subfamily Nematinae. Some of the larvae feed externally on plants and some form plant galls on willows (Salix species). In the case of the gall-forming species, when the female lays her eggs she injects a stimulant and the gall start to form before the eggs hatch. Most sawfly galls are hard and individual larva tend to inhabit the gall, feeding on the tissue and leave the gall to pupate in the soil. Most of the species are monophages although the type species, Euura mucronata, is polyphagous feeding on over thirty species of willow.
