Diptera, Agromyzidae

mine

Broad corridor, starting not far from the base of the blade, running upwards. Frass deliquescent, only few grains recognisable, mine greenish. Larva solitary. Pupation outside the mine.

hostplants

Poaceae, oligophagous

Bromus mollis; Hordeum vulgare; Secale cereale; Triticum aestivum.

phenology

Larvae in June (Hering, 1957a).

BENELUX

BE not recorded (Fauna Europaea, 2007).

NE recorded (de Meijere, 1928a, 1934a), initially as A. cinerascens.

LUX not recorded (Fauna Europaea, 2007).

distribution within Europe

From the UK, Denmark and the Baltic States southwards to the Iberian Peninsula and Serbia, but not south of the Alps (Fauna Europaea, 2007).

larva

Described by Darvas & Papp (1985a) and Darvas, Skuhravá & Andersen (2000a): mandibles each with 2 heavy teeth, front spiraculum with 11-14, rear spiraculum with 3 papillae. The papillae of the rear spiracula are elongated and S-shaped (d’Aguilar, Chambon & Touber, 1976a; Hering, 1957a, 1962a; Spencer, 1973b).

puparium

Uniformly reddish brown, rear spiracula on low protuberances, separated by their own diameter (d’Aguilar, Chambon & Touber, 1976a; Hering, 1957a, 1962a; Spencer, 1973b).

synonyms

Domomyza intermittens; Phytomyza secalina Hering, 1925; according to Darvas & Papp (1985a) also Agromyza b: Hering (1953a).

notes

Closely related with A. luteitarsis, and possibly the two are synomymous (Dempewolf, 2004a); in that case luteitarsis would be the valid name. Minor pest of cereal crops.
