Size estimated. I thought it was deer fly, but see comments--it is a soldier fly! The pattern is striking, with the bands on the abdomen and the orange-tinted wings, looks to be a mimic of the
honey wasp,
Brachygastra mellifica compare:
Well, following Eric's lead--now that I'm in the correct family, it looks a bit like a
Hoplitimyia--that's a hypothesis! Compare such images as:
This
reference mentions the neotropical
Hoplitimyia mutabilis as being part of a mimicry complex (with a species of
Meromacrus), flies having a yellow-tipped abdomen, mimics of the wasp
Pachyodynerus. A possibility?
Hmm. This
on-line paper (from Annals Ent. Soc. America, vol. 27, p. 443) describing the genus
Hoplitimyia gives a key to North American species, and if my individual above is in the correct genus, it would seem to key to
H. mutabilis, based on the yellow dorsal surface of abdominal segments 4-5, the rest being mostly black.

Well, this is one case where an expert confirms my wild speculation--see comment and thanks Martin!
Update 2/26/21. Comparing images here, this has to be a female--male has holoptic eyes. Photo also updated to larger version.
