Euura auritae is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae forms galls on willows (Salix species). It was first described by Jens-Peter Kopelke in 2000. E. auritae is one of a number of closely related species which is known as the Euura atra subgroup.

Description

The gall is an elongate swelling that tapers into the young shoot. It is 10 millimetres (0.39 in) to 15 millimetres (0.59 in) long by approximately 5 millimetres (0.20 in) wide. The bark around the gall is smooth and contains one larva which has three dorsal annulets on the third abdominal segment, and a suranal plate without pseudocerci. [1] [2] Pupation is probably in the gall. [1]

In Britain the gall has been found on eared willow ( Salix aurita ). [2] Elsewhere it has also been found on grey willow (S. cinerea), downy willow (S. lapponum) and (S. starkeana). [1]

Other similar looking galls in the Euura atra subgroup are, [3]

Distribution

Euura auritae has been recorded in central and northern Europe to Finland, Norway and Sweden. Also Czech Republic, Great Britain and the Netherlands. [1] [2] [3] [4]

<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 starts 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.

Euura amerinae is a species of sawfly belonging to the family Tenthredinidae. The larvae form galls on bay willow. It was first described by Carl Linnaeus in 1758.
