If you've ever watched a pond in the summer teeming with mayfly swarms, congratulations: you may have witnessed some of those bugs' lives in their entirety. Though their larval forms, called naiads, live up to a year in the water before becoming adults, fully-fledged mayflies have some of the shortest lifespans in the animal kingdom, lasting as long as a few days and as little as five minutes depending on the exact species. Virtually their entire adult lives are spent attempting to breed and lay eggs before dying.
