Delia flies are members of the Anthomyiidae family within the superfamily Muscoidae. The identification of different species of Delia can be very difficult for non-specialists as the diagnostic characteristics used for immature and/or female specimens may be inconsistent between species. Past taxonomic keys were not as comprehensive in their identification of Delia specimens; they were either too reliant on genetic characteristics, focused solely on a specific life stage, or were focused only on certain species. However current taxonomic keys aim to be more thorough by not only including morphological diagnostics for males, females, and immature specimens of various species, but also their genetic make-up or molecular barcode.
Pegomya is a genus of flies within the family Anthomyiidae. Some species are considered pests due to their leafmining larvae. Species include:

Actia maksymovi is a Palearctic species of fly in the family Tachinidae.
Actia dubitata is a Palearctic species of fly in the family Tachinidae.
Actia infantula is a Palearctic species of fly in the family Tachinidae.
Actia lamia is the type species of the genus Actia of the family Tachinidae.

Beris geniculata, the long-horned black legionnaire, is a European species of soldier fly.
Tachininae is a subfamily of flies in the family Tachinidae.
Ceromya flaviseta is a Palearctic species of flies in the family Tachinidae.
Ceranthia lichtwardtiana is a species of tachinid flies in the genus Ceranthia of the family Tachinidae.
Siphona geniculata is a Palearctic species of fly in the family Tachinidae.
Germaria angustata is a species of tachinid flies in the genus Germaria of the family Tachinidae.
Peleteria rubescens is a Palearctic species of fly in the family Tachinidae.
Pegomya winthemi is a species of fly in the family Anthomyiidae. Found in North America, it was first described as Anthomyia winthemi in 1829 by Johann Wilhelm Meigen. The insect measures 4.25–5 mm long. Its pedipalps are infuscated apically; the anterior lateral angles of the thorax and scutellum are yellowish red. The longest hairs of the arista are a little longer than its basal diameter, while the lower calyptra are distinctly protruded. The scutellum is almost bare on the disc. The posthumeral bristle is not duplicated, and the area between the posthumeral and the margin of thorax is almost bare.
Pegomya betae is a species of fly in the family Anthomyiidae. It is found in the Palearctic. For identification see
Delphinia picta is a species of picture-winged fly in the family Ulidiidae. The specific name picta is from Latin and means "painted." It is the only species in the monospecific genus Delphinia. It is found in the United States on the East Coast and in the Midwest from Florida to Maine across to Kansas through Minnesota but also can be found in Mexico and El Salvador. It is sometimes mistaken for a species of fruit fly, but D. picta do not feed on living plant matter, as they are detritivores and eat decaying plant matter. They also have been observed eating fermenting frass from Megacyllene robiniae on black locust trees. They can be found almost anywhere there is decaying vegetation: landfills, temperate deciduous forests, swamps, and even shaded fields.
Spelobia baezi is a species of fly belonging to the family of the Lesser Dung flies.
Neoascia geniculata is a Palearctic hoverfly.
