Rabdophaga Karschi
''Rabdophaga karschi'' is a Cecidomyiidae, gall midge which forms galls on the twigs of Willow, sallows (''Salix'' species). Description The genus ''Salix'' supports many galls, some of which are difficult to identify, particularly those caused by the gall midges in the genus ''Rabdophaga''. ''R. karschi'' forms galls on the twigs of sallows. The gall is an approximately 3 mm wide, slender, spindle-shaped swelling of a twig. There is one red larva or a pupa and the larva makes an exit hole in the galled stem or occasionally in a bud.

Jean-Jacques Kieffer
Jean-Jacques Kieffer (1857 in Guinkirchen – 1925 in Bitche) was a French naturalist and entomologist who specialised in the study of parasitic insects. Educated as a priest, Kieffer taught natural science in Bitche, Lorraine while working on the description and classification of insects. His work and publications later became a predominant source of description and classification for entomologists in the early 20th century, in particular with regard to parasitoid wasps, midges, and mosquitos. He collaborated with the English entomologist Peter Cameron. Kieffer received an honorary Doctor honoris causa degree from the University of Strasbourg in 1904.
