Kahis comment is appropriate for this non-typical muscid
"Thricops semicinereus (Muscidae). Most flies of this genus have an unusually anthomyiid- or fannid-like build for muscids. Males are easily identified by the conical, non-flattened abdomen being yellow with a black 5th tergite. F. canicularis is somewhat similar but it has a flattened abdomen and black 4.-5. tergite.

There's also a fundamental difference in habitat preference between these species: F. canicularis is found near farms and human dwellings, T. semicinereus is mainly a forest species."

This last fact is of forensic significance indicating a place of death or body removal.
