The Agromyzidae are a group of mostly small or minute flies, the larvae of which form mines or galls in plants. As a result, some species are economically significant pests, particularly those such as the vegetable leaf miner Liriomyza sativae that may attack a wide range of hosts. The majority of species, however, restrict themselves to a single host species or closely related host species only (Boucher 2010). Agromyzids are divided between the subfamilies Agromyzinae, in which the subcostal vein fuses with vein R1 before reaching the costa, and Phytomyzinae, in which the two veins reach the costa independently. The fossil record of the family is limited; however, feeding channels in wood similar to those formed by the modern genus Phytobia are known from the Upper Miocene (Spencer 1987).

Characters (from Boucher 2010): Minute to medium-sized flies (wing length 0.9–6.5 mm, usually 2–3 mm). Often yellow and/or black, brown or gray, few have some metallic greenish, bluish or coppery coloration. Head with first flagellomere small, round, or sometimes enlarged, elongate, or with anterodorsal projection or spine and with well-developed dorsobasal arista. Fronto-orbital and ocellar bristles trong; postocellar bristles divergent; fronto-orbital setulae in one or more rows, usually reclinate but sometimes proclinate, upright or absent; vibrissa well developed, some males with vibrissal fasciculus. Scutum with two to five dorsocentral bristles present but many genera in Phytomyzinae with three postsutural and one presutural dorsocentral bristles; acrostichals present (in up to ten rows) or absent. Costal break present near end of R1, humeral break absent; Sc incomplete distally or reaching C as linear fold, independently of R1, or Sc complete and fusing with R1 before reaching costa; CuA2 and A1 present, forming small cell cup; A1 not reaching wing margin. Abdomen tapered, composed of six visible segments. Females with abdominal segment 7 modified in large conical nonretractile oviscape.
