These amazing and so interesting creatures, dragonflies, are quite unlike other inhabitants of our planet. They appeared on Earth in times immemorial, but evolution considered them well enough adapted for life, so they have changed little in the intervening eras. Resembling small helicopters, they are found in a wide variety of countries and climates, except maybe in freezing climates.
