These spectacular insects are bedecked with iridescent green, red or blue colours and are often found flying or resting near quarry pools. They catch midges and small flies on the wing and take them to nearby vegetation to feed. The adults live for a few summer weeks while their larvae are underwater predators for up to three years. During this time they are sensitive to pollution, so their presence is a strong indication of good local water quality.
