Calyptrate flies
https://www.inaturalist.org/observations/41567988
"genus Musca has wing vein M bent near the tip of the wing to meet vein R4+5 (or nearly meet it) at the very edge of the wing (I'll have to let you look up those wing veins in a field guide or on the web, sorry). Your fly seems to have vein M run parallel to R4+5 without bending near the tip, which is actually true of most muscoid flies, but not genus Musca... :) Yours is more like this one:"

Open questions:
How closely related are bee flies and drone flies? https://www.fs.fed.us/wildflowers/pollinators/pollinator-of-the-month/drone_flies.shtml
why mimic bees? "there is one thing flies cannot do that bees can – sting!"

The following phylogeny is well-supported by multiple lines of evidence: mosquitoes | [bee flies | (drone flies | house flies)]
Yeah, mimicking bees (or hornets and other wasps) apparently avoids being a target for predators like birds.
Happy to help with other questions.
