Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sphaeroceroidea is a superfamily of flies. It includes the cosmopolitan families of Sphaeroceridae (small dung flies), Heleomyzidae, and Chyromyidae, as well as a few smaller groups. True flies are insects of the order Diptera (di = two, and ptera = wings). They possess a pair of wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax. The presence of a single pair of wings distinguishes true flies from other insects with "fly" in their name, such as mayflies, dragonflies, damselflies, stoneflies, whiteflies, fireflies, alderflies, dobsonflies, snakeflies, sawflies, caddisflies, butterflies or scorpionflies. Some true flies have become secondarily wingless, especially in the superfamily Hippoboscoidea, or among those that are inquilines in social insect colonies.
