Numerous microscopic photos of a very common fly found on the Gulf coast of Florida on beaches, particularly near Beach morning glory on sandy substrate. Many of these are a bit redundant so I didn't want to put them all on BugGuide but felt each would still be supplemental.

It is also on iNaturalist if anyone prefers that instead: https://www.inaturalist.org/observations/37291573

In addition, an associated male was found, probably lacking a ctenidium on the mid femora.

Sarcophagidae, but I think subfamily Sarcophaginae. The hairs on the arista are longer than expected in Miltogramminae and the eye is smaller.

I agree

Thanks! Face very similar to Sarothromyia spp., keys to it, and shares its ecology being associated with beaches as well. Will look at the catalogue and other references to see the species, if possible.

Sarothromyia is a subgenus of Tricharaea now. There might be a few species that are probably difficult to impossible to eliminate, but this might be femoralis or simplex.
