Whirligig Beetles

Scientific name: Dineutes and Gyrinus
(Coleoptera: Gyrinidae)

Facts: Whirligig beetles are found on ponds and streams. They congregate in large numbers and scurry about the water surface in a random pattern. When handled, these beetles give off an apple-like odor. Whirligig beetles are unique in that their compound eyes are divided, giving them a four-eyed appearance. This eye division allows them to see above and below the water surface at the same time.
