The larvae feed on the leaves of willow (Salix species). Description of the gallThese are simple galls with the leaf rolled, or folded downwards affecting one or both sides of the leaf. The female forms the gall before she lays her eggs, with the caterpillar feeding inside the fold. It will also feed on ungalled parts of the leaf, or other leaves.[1][2] The gall is usually found on bay willow (S. pentandra), and can also be found on gray willow (S. glauca) and tea-leaved willow (S. phylicifolia).[1][2] Redfern et al. state that, in Great Britain, it is safe to identify the galls of this species and Euura oblita by the foodplants. E. oblita feeds on crack willow (S. fragilis) and white willow (S. alba). In Great Britain, other Euura species do not form galls on these host plants.[1] DistributionThe sawfly has been found in Finland, Great Britain (England and Scotland), Ireland and Sweden.[1][3] References1. ^1 2 3 {{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}} 2. ^1 {{cite web|last1=Ellis|first1=W N|title=Euura destricta (MacGillivray, 1923)|url=http://bladmineerders.nl/parasites/animalia/arthropoda/insecta/hymenoptera/symphyta/tenthredinidae/euura/euura-destricta/|website=Plant Parasites of Europe|accessdate=2 March 2018}} 3. ^{{cite web|title=Phyllocolpa carinifrons (Benson, 1940)|url=https://www.gbif.org/species/8660116|website=gbif|accessdate=2 March 2018}} External links
