Rabdophaga jaapi is a species of gall midges which forms galls on creeping willow (Salix repens).
Description
The gall is an enlarged bud on S. repens. It is surrounded with small thickened leaves which have short silver-white hairs.{{cite book|last1=Redfern|first1=Margaret|last2=Shirley|first2=Peter|last3=Bloxham|first3=Michael|title=British Plant Galls|date=2011|publisher=FSC Publications|location=Shrewsbury|isbn=978-1-85153-284-1|pages=282–299|edition=Second}} Correct identification of the species of Salix is important for the identification of R. jaapi, because it is similar to R. rosariella, which forms galls on sallows.{{efn|In this case sallow refers to S. aurita, S. caprea and S. cinerea.}} The gall of R. jaapi can also be positively identified by the single reddish-yellow larva which has a sternal spatula, i.e. ″... a structure on the underside of the thorax of the final (third) instar larva of Cecidomyiidae...''″.{{cite web|title=Rabdophaga ?jaapi|url=http://www.dorsetnature.co.uk/pages-gall/g-181.html|website=Dorset Nature|access-date=18 November 2017}}
The species has one generation a year (i.e. univoltine) and the larva hibernates in the gall where it pupates.{{cite web|last1=Ellis|first1=W N|title=Rabdophaga jaapi|url=http://bladmineerders.nl/parasites/animalia/arthropoda/insecta/diptera/nematocera/cecidomyiidae/cecidomyiinae/lasiopteridi/oligotrophini/rabdophaga/rabdophaga-jaapi/|website=Plant Parasites of Europe|access-date=2 January 2018}}
