Robinia pseudoacacia.


The eggs are deposited in the youngest, still developing leaflets. A gall may harbour up to four whitish or pale yellow larvae. In the course of summer there are three or four generations. Pupation is in the gall, except for the larvae of the last generation, that leave the mine and hibernate in the soil.

Like its hostplant a North American species; appeared in 2003 for the first time in Italy, and has expanded since quickly over Europe.


Gall midges are parasitised in particular by Platygastriae, a family of wasps. As one of the few wasp groups Platygastridae demonstrate polyembryony: the fact that several larvae hatch from a single egg. Platygaster robiniae Buhl & Duso, 2008 is the platygastrid parasitising on O. robiniae in Europe.
