Description

There were quite a few of these resting on blades of grass, some in what appeared to be threesomes. I could never get a photo of these, but I was able to capture one of these clusters. It appeared to be two live flies and one dead one. A mating pair of dance flies with a nuptial gift? I had misidentified these as robber flies, but just read Loarie's and Kueda's comments to curiousgeorge and reconsidered my identification.

I think that's right. Might be worth posting to BugGuide to get a little further.

One more agreement....Family: Empidoidae; Genus Empis....Dance Fly...these are commonly found on buttercups in Spring time as well as in the tall spring time grasses in California for sure......I don't know about the rest of their range.
