Eulonchus marginatus is a species of small-headed flies in the family Acroceridae. [2] [3] [4] [5]
The Acroceridae are a small family of odd-looking flies. They have a hump-backed appearance with a strikingly small head, generally with a long proboscis for accessing nectar. They are rare and not widely known. The most frequently applied common names are small-headed flies or hunch-back flies. Many are bee or wasp mimics. Because they are parasitoids of spiders, they also are sometimes known as spider flies.
Acrocerinae is a subfamily of Acroceridae. They are small distinctive flies whose larvae are endoparasites of spiders. Adult hunchback-flies visit flowers to feed on nectar. Traditionally the subfamily included the genera now placed in Cyrtinae and Ogcodinae, but the subfamily in this sense was found to be polyphyletic and was split up in 2019.
Philopotinae is a subfamily of small-headed flies. Their larvae are endoparasites of araneomorph spiders in the subgroup Entelegynae.
Panopinae is a subfamily of small-headed flies (Acroceridae). Their larvae are endoparasites of spiders in the infraorder Mygalomorphae.
Acrocera is a genus of small-headed flies in the family Acroceridae. There are around 50 described species in Acrocera.
Acrocera subfasciata is a species of small-headed flies in the family Acroceridae.
Ogcodes is a genus of small-headed flies in the family Acroceridae. About 90 species have been described for the genus.
Eulonchus halli is a species of small-headed flies in the family Acroceridae. It was named after one of its original collectors, Jack C. Hall, who was also a colleague of the species's author, Evert I. Schlinger, at the University of California.
Eulonchus is a genus of small-headed flies in the family Acroceridae. There are six described species in Eulonchus. The genus is found in North America. Adults have a metallic blue, green or sometimes purple coloration, giving them a jewel-like appearance. A common name for flies in the genus is the North American jewelled spider flies. Adults are also known as "sapphires" or "emeralds".
Pterodontia is a genus of small-headed flies. There are at least 20 described species in Pterodontia.
Turbopsebius is a genus of small-headed flies in the family Acroceridae. There are about four described species in Turbopsebius.
Pterodontia flavipes is a species of small-headed flies. Adult males are 5.5–10.5 mm in size, while adult females are 5–9 mm. The larvae are thought to enter their host spiders at the leg articulations. First instar larvae of the species have also been recorded attacking the mites Podothrombium and Abrolophus.
Ocnaea is a genus of small-headed flies. There are at least 20 described species in Ocnaea.
Lasia is a genus of small-headed flies in the family Acroceridae. There are about 19 described species in Lasia, which are distributed in the New World.
Eulonchus sapphirinus is a species of small-headed flies in the family Acroceridae.
Eulonchus tristis is a species of small-headed flies in the family Acroceridae.
Archocyrtus is an extinct genus of small-headed flies in the family Acroceridae. The genus is known from compression fossils from the Late Jurassic Karabastau Formation of Kazakhstan. The genus is the only member of the subfamily Archocyrtinae.
Ogcodes pallidipennis is a species of small-headed flies in the family Acroceridae.
Apsona is a genus of small-headed flies. It contains only one species, Apsona muscaria, which is endemic to New Zealand. It is very similar to the North American species Eulonchus smaragdinus.
Cyrtinae is a subfamily of the Acroceridae. Their larvae are endoparasites of araneomorph spiders in the subgroup Entelegynae.
