Liriomyza is a diverse genus of leaf-mining flies feeding on a wide range of plant hosts, with the highest diversity of species found in northern temperate regions (Boucher 2010).
Characters (from Boucher 2010): Frons and scutellum usually bright yellow (either or both occasionally dark); lunule not especially high or large; three (sometimes two) postsutural and one presutural dorsocentral bristles; M1 ending closer to wing tip than R4+5; knob of halter completely white or yellow; male usually with stridulatory mechanism on membrane connecting abdominal tergites and sternites; surstylus usually present, with one or two (rarely three) spines and sometimes few weak hairs; epandrium often with one or two (sometimes more) spines at posteroventral margin, or conspicuously sclerotised on inner margin.
