larva

mine

Oviposition at the leaf underside. Initially a full depth gallery with an irregular course and width. Frass here in a central, only rarely interrupted, pearl chain. Later the mine develops into a very irregular, full depth blotch with only a little frass in loose grains. Probably the larva can leave its mine and restart elsewhere (getting rid of its frass in the mean time), because attacked leaves show loose silk at their surface. The larva mines it entire life; pupation is external.

BENELUX

BE Found by Chris Snyers in in 2011 in Belgium mining in the open air, not far from a tomato greenhouse where already in 2010 an infestation had occurred.

NE NE Found in 2914 by Jan Scheffers in the open, also on a wild plant (Solanum nigrum). Fond vy him in 2016 in the dunes on Solanum dulcamara, nigrum, and triflorum.

LUX not recorded.

distribution within Europe

southern Europe; originally a species from Latin America.

larva

notes

In southern Europe, where the species has been accidentally introduced, a serious pest on potatoes and tomato. In the first case because of damage to the foliage, in the case of tomato mainly because the larvae also attack the developing fruits.
