Euura proxima (

Synonyms | |
Pontania proxima (Lepeletier, 1823), Nematus proximus Serville, 1823 |
Euura proxima is a species of sawfly belonging to the family Tenthredinidae (common sawflies). The larvae feed on the leaves of willows ( Salix species), creating galls. It was described by Jean Guillaume Audinet-Serville in 1823. The species was placed in the genus Euura in 2014 [1] and was previously known as Nematus proximus and Pontania proxima.
The gall is an ovoid, bean-shaped gall, up to 12 mm x 6 mm in size, with a hard thick red wall when occupied. The gall is formed when the female lays her eggs and injects a substance into the leaf. At first the galls are green and the walls soften as the larva consumes the tissue. Some galls may not be occupied, possibly because an egg was not laid or it did not hatch. [2] There can be several galls to a leaf and they do not usually touch the midrib. Galls of E. proxima are found on white willow ( S. alba), weeping willow ( S. babylonica), S. x blanda, S. excelsa, crack willow ( S. fragilis) and bay willow ( S. pentandra). [3] There are two broods in a year with the first brood maturing around mid-summer and the second in the autumn. [2]
E. proxima is one of three closely related species in the Euura proxima group. The other members of the group are,
The following species are inquilines of E. proxima,
This species is found throughout Europe, north to southern Finland and east to the Caucasus. It has been introduced to Australia, North America and New Zealand. [4]
