Rabdophaga terminalis
Rabdophaga strobilina is a gall midge which forms galls on the buds of some species of willow. It was first described by Hermann Loew in 1850.
Description
The gall is green, reddish, later black but never hairy. The leaves of the terminal bud are slightly thickened, sometimes crinkled and curled into an elongate gall, which can be hidden by older leaves. Inside the gall is an elongate cavity with orange or reddish larvae numbering from one to forty.It is uncertain whether white larvae are the young larvae of R. terminalis or inquilines, Macrolabis saliceti and/or R. strobilina.
The gall has been found on the following species:Salix alba – white willowSalix babylonica – Babylon willowSalix caesia Salix excelsa Salix × fragilis – crack willowSalix pentandra – bay willowSalix purpurea – purple willowSalix triandra – almond willowSalix viminalis – osier
