The nymphs of these predators live underwater, and can hunt tadpoles and small fish by thrusting their lower jaw outward to impale their prey (they look nothing like their more famous adult form). As adults, these aerial predators are harmless to humans, but hunt many pests. Often times living in and strongly associated with wetlands, identify these insects of the order Odonata, suborder Anisoptera, so named because the long pair of hindwings are wider than their long pair of forewings.
