Agromyza mobilis Meigen, 1830

mine

Long upper-surface corridor usually containing several larvae that graze shoulder to shoulder from the leaf tip downwards. Pupation outside the mine. Mines and larvae are indistinguishable from those of A. nigrella.

hostplants

Poaceae, broadly oligophagous

Alopecurus pratensis; Arrhenatherum elatius; Avenula; Brachypodium sylvaticum; Briza; Bromopsis ramosa; Calamagrostis; Echinochloa crus-galli; Festuca; Holcus; Hordeum murinum, vulgare; Lolium; Milium effusum; Phalaris; Phleum pratense; Poa; Secale cereale, Triticum aestivum.

Because of confusion with A. nigrella many of these associations need confirmation. Spencer (1973b) accepts only Triticum as a host plant; Beiger (1989a, Poland): Hordeum, Secale, Triticum; Pakalniškis (2000a, Lithuania): Brachypodium, Echinochloa and Triticum.
