Golden-backed snipe fly

This golden-backed snipe fly (Chrysopilus thoracicus) landed in one of my bird baths and drifted around for a few minutes on the surface tension. I’m not positive, but I think I’ve seen them do this in past years, too. I wonder whether they are looking for mosquito larvae, or perhaps adults. These flies have predaceous mouthparts, so they clearly hunt something. Sure wish somebody would PCR the gut contents of these things and let me know. Anyone ever seen them take something down?

Here’s another one, albeit one with a damaged eye:

Copulating robber flies, with snack

Two rather large (almost 2″) robber flies mating on rabbitbrush in Madras, Oregon.¬† Male has a longhorn beetle (perhaps Crossidius hirtipes?) as a nuptial gift. I don’t know the species, unfortunately.
