They swarm like gnats, but look like ants? - Lasioglossum - Male
Salt Lake City, Salt Lake County, Utah, USA
July 10, 2007
Size: 5mm long
There a tons of these little bugs swarming around the front and side of my house. They fly a bit like gnats, and seem to swarm similarly to gnats, but as individuals look a bit like ants. What are they? Are they harmful to houses or gardens? What attracts them? There are so many it is almost unpleasant.

Small sweat bees (males)
Members of the morio-group of genus Lasioglossum. Sweat bees have a peculiar life-cycle, where males appear only once during the season, but then often in quite large numbers. "Yours" were likely patrolling around the nesting holes of their colony, waiting for emerging females. They are by no way harmful, despite the nuisance due to their number; Moreover, the mating season won't last for very long.

Lasioglossum (Dialictus)
males

I don't think our species actually belong to the morio subgroup of the smeanthmanellum group
