Hi. Here are the shots of that robber fly I mentioned, taken July 15, 2009. S/he’s just over an inch long.
Though your most recent visitor is a Tachinid Fly rather than a Robber Fly, this impressive specimen from several years ago really is a Robber Fly, more specifically a Bee Killer, Mallophora fautrix. According to BugGuide, it is the only member of its genus found in California. Bee Killers are large Robber Flies that attack on the wing Bees, Wasps and other large flying insects.
