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.[2] Adults are also known as "sapphires" or "emeralds".[3]

Species
editThese six species belong to the genus Eulonchus:[2]
- Eulonchus halli Schlinger, 1960[4] (Hall's sapphire)
- Eulonchus marginatus Osten-Sacken, 1877[5] (Sombre Sapphire or Emerald)
- Eulonchus marialiciae Brimley, 1925[6] (Mary-Alice’s Emerald, Mary Alice's small-headed fly)
- Eulonchus sapphirinus Osten Sacken, 1877[5] (Northern Sapphire or Emerald)

- Eulonchus tristis Loew, 1872[7] (Dusky Sapphire)
Distribution
editMost species of Eulonchus are distributed west of the Rocky Mountains in the United States, northwards to Canada and southwards to Baja California, Mexico. The exception is Eulonchus marialiciae, which is known only from a small area in the Great Smoky Mountains in North Carolina, though future studies are needed to confirm the species' true range.[2]
Hosts
editFlies in the genus attack spiders in the families Euctenizidae and Antrodiaetidae.[2]
