Aquatic beetles include whirligig beetles (family Gyrinidae), water scavenger beetles (family Hydrophilidae) and diving beetles, or true water beetles (family Dytiscidae). Native to temperate and tropical regions throughout the world, whirligig beetles spend most of their lives on the water's surface. Named for their characteristic whirligig dances, these unusual insects congregate in large numbers, rushing in zig-zag paths past one another. There are over 450 species of whirligig beetles. Abundant in warm, marshy areas of the world, water scavenger beetles are awkward swimmers, using first the middle and hind legs of one side, then those of the other. About 2,000 species of water scavenger beetles are known to exist. Widespread in quiet streams and ponds, diving beetles range up to two inches in length. Characterized by smooth, oval bodies and hairy, oarlike hind legs, diving beetles have hardened wing covers that form a cavity above the body. Air is trapped in the cavity, allowing the beetle to breathe while submersed. The ferocious-looking larvae sports huge fangs, earning it the nickname "water tiger." There are over 2,500 species of diving beetles.
