Looks like a phorid (humpback) fly to me. If it is, look for decaying organic matter in trash or, worse, a leaking sewer pipe somewhere. Common breeding sites include floor drains, trash containers, elevator pits and garbage disposals, and where drain or sewage pipes have broken under slabs or in crawl spaces.

We started seeing these flying insects in one of our cellar-level storage spaces last month and have been unable to identify them and what may be causing them (see attached images). The Seek app suggests that they are Humpback flies, but we aren't sure. Is that correct? Thanks!
