The larvae feed within the leaf-stalk (petiole), or midrib of a leaf, on willows (Salix species) forming a gall. The sawfly was first described by Carl Gustav Alexander Brischke in 1883. E. testaceipes is one of three closely related species known as the Euura amerinae species subgroup. The other members of the group are E. amerinae (Linnaeus, 1758) and E. venusta (Brischke, 1883)[1] Description of the gallThe spindle-shaped or ovoid gall is formed in the petiole or midrib of a leaf and is 10 mm long and 5 mm wide and contains one larva. It can be found on white willow (S. alba), Babylon willow (S. babylonica), S. blanda, crack willow (S. fragilis) and almond willow (S. triandra).[2][3] There can be several galls on a leaf.[3] DistributionThe sawfly has been found in Great Britain, the Netherlands and Poland.[1][2][3] References1. ^1 {{cite journal|last1=Liston|first1=Andrew D|last2=Heibo|first2=Erik|last3=Prous|first3=Marko|last4=Vardal|first4=Hege|last5=Nyman|first5=Tommi|last6=Vikberg|first6=Veli|title=North European gall-inducing Euura sawflies (Hymenoptera, Tenthredinidae, Nematinae)|journal=Zootaxa|date=2017|volume=4302|issue=1|pages=54–57|url=https://doi.org/10.11646/zootaxa.4302.1.1|publisher=Magnolia Press|issn=1175-5334}} 2. ^1 {{cite book |last1=Redfern |first1=Margaret |last2=Shirley |first2=Peter |last3=Boxham |first3=Michael |title=British Plant Galls |date=2011 |publisher=Field Study Council |location=Shrewsbury |isbn=978 185153 284 1|pages=282–299 |edition=Second}} 3. ^1 2 {{cite web|last1=Ellis|first1=W N|title=Euura testaceipes (Brischke, 1883)|url=http://bladmineerders.nl/parasites/animalia/arthropoda/insecta/hymenoptera/symphyta/tenthredinidae/euura/euura-testaceipes/|website=Plant Parasites of Europe|accessdate=11 March 2018}} External links
