I wish the photo was better quality... these flies are only 3.0-3.5mm long... last week or so, I've been finding about a hundred a day floating in my kids' pool. The large stilleto-type proboscis suggests a biting fly, but nobody has complained of small biting flies... a predator of some type..?? The tapered abdomen, & small size suggests perhaps a snipe fly..??... 4-segmented antenna looks similar to a 'horse-fly'... suggestions most welcome. BTW... the specimens in the photo are floating in alcohol... the abdomen has swollen & 'exploded' from being in the water.... wish I had a microscope adapter for my digital camera; a +3 close-up adapter just doesn't give the detail I would like.
