Rabdophaga rosariella


Rabdophaga rosariella is a species of gall midge which forms galls on sallows. It was first described by Jean-Jacques Kieffer in 1897.

Description

The gall is a small rosette, most often in an axillary bud on sallows. In Britain sallow usually refers to S. aurita, S caprea, S. cinerea and the hybrids between these species. The rosette leaves are not obviously hairy and the full grown larva does not have a sternal spatula. Larvae of R. rosariella are unique as all other known Rabdophaga larvae have a sternal spatula.

Distribution

Recorded from Belgium and Great Britain.
