Sunburst Diving Beetle

Thermonectus marmoratus

This pretty beetle swims in groups and is brightly colored to advertise bad taste. It is streamlined, has powerful oar-like hind legs for propulsion, and steers with its short forelegs. Like many aquatic insects, it carries surface air beneath its wings to breathe under water. It can also fly!
