The Ulidiidae or picture-winged flies are a large and diverse cosmopolitan family of flies (Diptera), and as in related families, most species are herbivorous or detritivorous. They are often known as picture-winged flies, along with members of other families in the superfamily Tephritoidea that have patterns of bands or spots on the wings. Some species share with the Tephritidae an unusual elongated posteroapical projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Two species, Tetanops myopaeformis and Euxesta stigmatias, are agricultural pests.
Tritoxa is a genus of picture-winged flies in the family Ulidiidae.
Euxesta abana is a species of ulidiid or picture-winged fly in the genus Euxesta of the family Ulidiidae. It was described by Charles Howard Curran in 1935. The species can be found at White Sands National Park in Tularosa Basin, New Mexico.
Euxesta annonae is a species of ulidiid or picture-winged fly in the genus Euxesta of the family Ulidiidae. The species can be found from Orlando, Florida to Hawaii, where it feeds on corn.
Tritoxa cuneata is a species of picture-winged fly in the genus Tritoxa of the family Ulidiidae.
Tritoxa incurva is a species of picture-winged fly in the genus Tritoxa of the family Ulidiidae.
Tritoxa pollinosa is a species of picture-winged fly in the genus Tritoxa of the family Ulidiidae.
Tritoxa ra is a species of picture-winged fly in the genus Tritoxa of the family Ulidiidae.

Euxesta nigricans is a species of ulidiid or picture-winged fly in the genus Euxesta of the family Ulidiidae. It was described by Frederik Maurits van der Wulp in 1899. It can be found in Guerrero, Mexico.
Euxesta nitidiventris is a species of ulidiid or picture-winged fly in the genus Euxesta of the family Ulidiidae. Larvae are known to be pests of maize.
Tritoxa flexa is a species of picture-winged fly in the genus Tritoxa of the family Ulidiidae.
Herina is a genus of flies in the family Ulidiidae. It is possibly the largest genus in the family.
Otitinae is the name of a subfamily of flies in the family Ulidiidae. It was formerly the Otitidae. Like the Ulidiinae, most species are herbivorous or saprophagous. Most species share with the Tephritidae an unusual elongated projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Most are dull gray to shiny brown or black flies with vein R1 setulose or, in a few cases, bare.

Ortalis is an historic genus of Ulidiid or picture-winged flies, first described by Fallén in 1810. It served as the type genus for the family Ulidiidae, which was called Ortalidae at the time. In 1932, it was pointed out by Adlrich that the name Ortalis was preoccupied by a genus of birds which had been named by Merrem in 1786. The name of the fly family was therefore revised, with some authors calling it Otitidae until Ulidiidae was settled on as standard. The genus itself was found to be paraphyletic, and all of its species have been reassigned to other genera, some in the Ulidiidae, and some in other Tephritoid families. In the following list, the species are organized according to the families and genera to which they have been reassigned.
Myennidini is a tribe of picture-winged flies in the family Ulidiidae.

Tritoxa californica is a species of picture-winged fly in the genus Tritoxa of the family Ulidiidae.
Tritoxa decipiens is a species of picture-winged fly in the genus Tritoxa of the family Ulidiidae.
