Predaceous Diving Beetles

LIVE PREDACEOUS DIVING BEETLES Aquatic Insect Predators from the Family DytiscidaeVibrant, active, and utterly lethal — these beetles are as fascinating as they are ferocious. These aquatic beetles are the torpedoes of the insect world — fast, air-breathing predators with a thirst for motion... and meat. APPEARANCE Streamlined, oval-shaped body Glossy black, brown, or bronze carapace (species dependent) Powerful, paddle-like hind legs adapted for swimming Adults range in size from 1 to 3 cm Some species display metallic or iridescent coloration HABITAT Native to ponds, marshes, and slow-moving streams Thrive in still or gently flowing freshwater with aquatic vegetation Require access to the surface for air (they store air under their wing covers) BEHAVIOR Aggressive hunters — both adults and larvae (called “water tigers”) Strong swimmers using rhythmic strokes of their hind legs Adults can fly and are attracted to light at night Solitary, territorial, and best kept individually
