Agromyza pseudoreptans Nowakowski, 1967
Urtica doica, Duin en Kruidberg
Urtica doica, Nieuwendam
Full depth corridor (unusual for an agromyzid!), mostly beginning at the leaf margin, and never starting with a closely set, “intestine-like”, number of curves. Further on the corridor considerably widens, mostly keeping close to the leaf margin. Often several larvae in a mine. Frass in lumps or short rods, never in long threads. Pupation outside the mine
Urticaceae, oligophagous (?)
The occurrence on Humulus and Parietaria needs confirmation.
Larvae in the Netherlands found from early May till early November; possibly in a spring and in a (much stronger) autumn generation. However, Scheirs, De Bruyn & von Tschirnhaus (1996a) consider the species univoltine, with adults in late summer.
BE recorded (Scheirs, De Bruyn & von Tschirnhaus; 1996a).
NE recorded (Ellis: numerous localities).
LUX recorded (Ellis: Kautenbach).

Agromyza urticae Nowakowski, 1964.
Only in 1964 Nowakowski (1964a) discovered that the classical species A. reptans was a mix of two: A. reptans Fallén and an undescribed species, that received the name A. urticae. Because it turned out that this name already was in use, shortly after the replacement name A. pseudoreptans was coined.
A. reptans is in our region very much rarer than pseudoreptans (Martinez, 1984a; Spencer 1976a, also own experience). Older references to reptans most probably therefore concern pseudoreptans.
