Common Name: Whirligig Beetles
Description: Whirligig beetles are some of the fastest aquatic beetles in Coleoptera. Middle and hind legs propel them through the water. Front legs are used for grasping prey and steering their elongate bodies. They are most distinguishable by their divided compound eye, where one half looks up and the other half looks down. Also unique to this family is the short, clubbed antennae. Adults and larvae are predaceous and feed on insects that fall into the water. The adults also produce a fruity odor when handled.
