Dragonflies are ideal organisms for naturalists to study. The adults, as striking and colourful as the birds with whom the share the air, have complex and interesting territorial, mating and egg laying behaviour. Compared to many other insects, they are large and easily observed. Study of the larvae, amount the more important of the smaller aquatic carnivores, introduces the observer to fascination of fresh-water ecology.
