Adults feed on midges, mosquitoes, small moths and the larger dragonflies can capture bees, butterflies and other dragonflies.
Nymphs feed on small aquatic organisms, and occasionally tadpoles and small fish.
Dragonflies and damselflies are long, narrow insects 20-125 mm long, often beautifully coloured. The head is large with very large eyes and the abdomen is long and slender. They have four wings that are elongate, many-veined and membranous. The antennae are very small and bristle-like. Odonata have chewing mouthparts.
