The Predaceous Diving Beetle is common in lakes, ponds, and vernal pools. This shiny, brownish-black beetle is a strong flier and eats insects or other small water organisms. Predaceous Diving Beetles are also ferocious predators. Their larvae are also ferocious predators. More than 300 species are found in N. America.
