Female Snake Flies can be easily distinguished from the males by their very long and flexible ovipositor, sometimes mistaken as a "tail" or "stinger". They do not sting and are harmless to humans. They eat small insects, and while eating the female tends to wave her ovipositor back & forth, seemingly "in enjoyment". In North America (north of Mexico) snakeflies mostly occur to the west of the Rockies.
