Despite their size, these bugs are evolutionary marvels. The common midge can beat its wings over 1,000 times per second. That’s faster than a hummingbird, which is basically a tiny helicopter. Your fruit fly can also accelerate faster than a fighter jet during takeoff when you try to smack it.
And here’s the kicker: some species of black gnat can detect a single molecule of carbon dioxide from over 50 feet away. You can’t hide. You can’t hold your breath forever. They always find you.

The females fly into the swarm, grab the hottest gnat, and then everyone immediately goes back to bothering you. It’s the most efficient romance in the animal kingdom.
