Agromyza reptans

Urtica dioica, Rhenen; “head” and detail of the cephalic skeleton. The anterior arm is red-brown basally (difficult to fotograph)

the spinulation (left a segment, right the “hip”) is much weaker than in pseudoreptans

in front of the mandible is a median spathulate organ; in pseudoreptans this is branched. Perhaps also characteristic of reptans is a dark arrow-shaped organ behind the mandibles. It is internal, and looks serrate under some angles

front and rear spiraculum (dorsal, lateral)

abdomen end, lateral and ventral

The larva is described by Beri (1971c) en Dempewolf (2001a), probably also by de Meijere (1925a, as reptans); see also Starý (1930a).
