Something iNat has been immensely useful for is helping me to determine the range of different species or groups of species. However, I recently learned about Chyromyidae, or Golden Flies, which seem to be an unfortunate exception. There are very few observations of flies within this family on iNat,…

What part of the world are you interested in?

If you didn’t already see it, there seems to be a key to genus, presumably for N.America, here : https://bugguide.net/node/view/102694 [image] Mercedes-Fletcher: There are very few observations of flies within this family on iNat, and even fewer have reached research grade. Unfortunately th…

I thought you had misspelled Chironomidae!! As well as the resources mentioned above, the Bugguide Family page is here - Family Chyromyidae - BugGuide.Net . It really doesn’t say much. You could also search Google Scholar for papers about the Family. One of the things about flies is that finer ident…

Well, I’m always curious to learn as much as I can about things so any information would be nice, though I was the most interested in figuring out which genus/genera could be found in the US, particularly the midwest.

This probably isn’t much use to you in that case, as I think they are all British: Collin, J.E. 1933. Five new species of Diptera. Entomologist’s Monthly Magazine, 69: 272–275. As someone has already said, there is plenty of more modern info available through Google Scholar.

According to the Manual of Nearctic Diptera : The family consists of three genera, Chyromya, Gymnochiromyia, and Aphaniosoma, all of which occur in the Holarctic, Ethiopian, and Oriental-Papuan regions; 15 of about 40 known species occur in North America. The genus Chyromya has many synonyms and mi…

Also try the website Diptera.info. It has an extensive photo gallery and is frequented by international experts who are often willing to send pdfs.

Thank you for the help! So all three genera occur in North America? Do specific genera occur only in certain regions of North America or can any of them be found anywhere? If it’s the former, could you find the details of that?

Yes, the MND lists all three genera as “widespread”, so they can be found throughout the continent.

Hmm. I suspected range might be a way to help determine genus but it seems I was mistaken. Thank you for clarifying :)
