 The gall-wasp "Periclistus brandtii" causes no gall itself, but deposits its eggs in the bedeguar tissues on which the larvae feed.In turn, these larvae may be parasitised by a chalcid wasp, "Eurytoma rosae", which works its way from one inquiline's cell to the next.The parasitoid ichneumon "Orthopelma mediator" lays its eggs directly into larvae of "D. rosae", killing them.
