Bumblebee fly

We're blessed with lots of bumble bees, which I'm in the beginning stages of learning to identify. But while this critter is a pretty darn good bumble bee mimic, I wasn't fooled. The beetle impaled on the insect's piercing mouthparts was, and it was a fatal mistake. The prey is in the process of being eaten by an Asilid fly of the genus Laphria. The "robber flies" are all fierce predators that pounce on other insects taken in by their seemingly gentle, bumble bee-like demeanor. The asilid then stabs its victim with a stiletto beak that injects a slurry of neurotoxins and digestive enzymes that cause instant paralysis and quickly turn the internal organs to a soup, which is drained to the last drop by the fly. Unlike, say, deer flies, asilids don't bite people. Still, they're more than a little creepy, so I keep my distance. I don't want the predators to discover human flesh. I view them through a telephoto lens.
