Characters

Minute to small (1.3-4.5 mm), slender flies, yellow to black sometimes with dark spots or stripes; wing usually long and narrow. Arista pubescent or with longer rays; ocelli present; Ocellar bristles present; Postvertical bristles small, converging, rarely absent; 2-3 pairs of frontal bristles, curving backward, usually preceded by 1 or more weaker bristles; interfrontal bristles absent or present; vibrissae present. Wing usually clear, sometimes marked; vein C with subcostal break; vein Sc incomplete; crossvein BM-Cu present but sometimes not complete; cell cup closed, rarely open. Some genera, including the more common Anthomyza and Paranthomyza, with femur of fore leg with a short spine on the ventral side, beyond the middle; tibiae without dorsal preapical bristle.

Biology

The larvae of most species develop in the stems and leaf sheaths of grasses and plants in marsh habitats such as species of Typha, Juncus, Carex and Scirpus without causing much damage; several species are known to mine in dicotyledons whereas others live in dead plants or as inquilines in existing galls. Adults of most species are usually found in moist habitats, both shaded and in the open such as damp meadows, marshes, bogs and damp deciduous or mixed forests with rich undergrowth; a preference for more dryer habitats such as dry grasslands is shown by some species of Anthomyza and the brachypterous Stiphrosoma sabulosum (Haliday).
