Many dance flies present prey as nuptial gifts as a part of their mating rituals, but as Powell and Hogue write in California Insects, "The strangest habits are exhibited by a few species in which males secrete material from the digestive tract which is formed into a frothy, white ball or "balloon". This balloon either entraps a small prey or is substiuted for prety in the courtship gift-giving sequence" (p. 161). This balloon clearly has prey within, perhaps some kind of hemipteran.

Ron and I were pretty flabbergasted as we watched these two engage in mid-air copulation, their aerial control so perfect that I was able to get this picture even though each fly couldn't have been more than 7 mm long.

Jack Owicki has this great BG photo that spawned an even greater discussion: http://bugguide.net/node/view/267952/bgimage.

I suspect this is Empis and not another genus in Empidinae due to the balloon-forming behavior and the long proboscis, but I'd love correction! Habitat was very close to a running creek, vegetation was riparian, some willow, but mostly oaks and maples.

I think I've had trouble convincing myself that C. exigua and C. gypsophiloides are different, but if this is C. exigua then the flower is much smaller and less colorful than C. gypsophiloides. Ron seemed pretty confident about it.
