Agromyza hendeli Griffiths, 1963
Three or four eggs are deposited in a row, at right angle to the leaf margin. After hatching each of the larvae makes a corridor in the direction of the leaf tip. The corridors widen, and fuse into one upper-surface blotch. Frass in comparatively large lumps. Pupation as a rule outside the mine.
Larvae in June and August (Hering, 1957a), in two generations (Griffiths, 1962a).
BE recorded (Scheirs & De Bruyn, 1992a).
NE recorded (de Meijere, 1925a).
LUX not recorded (Fauna Europaea, 2007).
distribution within Europe
From Sweden to Italy, and from the UK to the Baltic States and Slovakia (Fauna Europaea, 2007).
Rear arms of the cephalic skeleton strongly sclerotised, brown or black. Rear spiracula separated by about their diameter. The larva is described by Griffiths (1963a) and de Meijere (1925a, as nigripes); the supplementary description by de Meijere (1943a) contains mistakes.
The dark rear arms of the cehalic skeleton easily separate the larvae of this species from those of A. phragmitidis, that also lives on Phragmites. However, there still is no way to distinguish the larvae of hendeli from those of the rare A. spenceri.
Agromyza nigripes: de Meijere (1925a), A. lucida: Hering (1957a) [Griffiths, 1963a].
A. hendeli belongs to the A. nigripes species group of Griffiths (1963a).
