Insects have appeared in mythology around the world from ancient times. Among the insect groups featuring in myths are the bee, fly, butterfly, cicada, dragonfly, praying mantis and scarab beetle. Insect myths may present the origins of a people, or of their skills such as finding honey. Other myths concern the nature of the gods or their actions, and how they may be appeased. A variety of myths tell of transformations, such as between the soul of a living or dead person and a butterfly in Japan. Finally, insects appear as symbols of human qualities such as swiftness, or as portents of forthcoming trouble; accordingly, they may appear as amulets to ward off evil.
