Hi, Gary.

If the black flies were pretty small, like house flies, they may have
been stable flies (Stomoxys irritans), which seem to be ubiquitous
wherever there are large mammals. Check that species out on the web.
Most deer flies out here are yellow or brown, as you say. Only the
huge horse flies are black. Or if they were tiny, they could have
been true black flies (Simuliidae), which live around streams and
don't seem to be as common here as in the East and farther north. All
of them seem to relish human blood, and we really should know what is
eating us!
