Agromyza alunulata larva

Agromyza alunulata larva

Glyceria maxima, England, near London; from Hering (1955a, as A. distorta); a : cephalic skeleton; b : frontal region of head; c : frontal spiraculum; d : rear spiraculum; e : part of the spinulation of the first abdominal segment, lateral; scale line is 0.1 mm.

The larva is described (as Agromyza distorta) by Hering (1955a) and Griffiths (1955a, 1963a). Very striking are the enormously enlarged, disclike, front spiracula with 200-250 papillae, probably an adaptation to the very wet habitat of the hostplant. The mandible has the unusually high number of 5 teeth. Rear spiracula, with 3 papillae, very close to each other, almost touching. Placed by Griffiths (1963a) in his A. nigripes group.
