Plant Parasites of Europe

leafminers, galls and fungi

Agromyza anthracina larva


Urtica dioica, Duin en Kruidberg


front and rear spiraculum, lateral


front and rear spiraculum, dorsal


mandibles, and spinulation of the ‘hip’


Urtica dioica, Nieuwendam; cephalic skeleton and mouth field


abdomen end ventral and (weaker magnification) dorsal

Mandibles with 3 teeth that hardly or not alternate. Rear spiracula on a common base, touching each other, with 3 papillae, separated by 3 flattened, fan-shaped, distally deeply cleft, “hairs” (visible only under strong magnifications).

De Meijere (1924a) and Nowakowski(1964a) describe the mandibles as 2-toothed and alternating. However, SEM-pictures by Dempewolf (2001a) clearly show that the mandibles are 3-toothed and not alternating, as is obvious also in the ©s above. Dempewolf also found that the fan-shaped setae on the rear spiracula are not limited to A. pseudoreptans, as was stated byNowakowski, but occur in all three Nettle-mining Agromyza‘s. (For anthracina this was depicted already in de Meijere’s publication.

The “hips” are much less developed in comparison to A. reptans and pseudoreptans.
