Snakeflies (order Raphidioptera) are interesting creatures. I like to call them "dinosaur bugs" because they're a group of insects that evolved in the early Jurassic, reaching peak diversity during the Cretaceous. Snakeflies are what's known as a relict group, meaning they used to be way more widespread than they are now. They're a remnant of a more abundant past. These insects undergo complete metamorphosis. Both the larva and the adult are predators of soft-bodied arthropods. Snakeflies have four wings, so they're neither flies nor snakes :-) Agulla sp., Northern California.
