Summary 5

The family Scarabaeidae as currently defined consists of over 30,000 species of beetles worldwide. The species in this large family are often called scarabs or scarab beetles. The classification of this family is fairly unstable, with numerous competing theories, and new proposals appearing quite often. It is probable that many of the subfamilies listed here will not be recognized very much longer, as they will likely be reduced in status below subfamily rank, or elevated to family status (the latter is most likely, e.g., with the family "Melolonthidae" already appearing in some recent classifications). Other families have been removed recently, and are nearly universally accepted (e.g., Pleocomidae, Glaresidae, Glaphyridae, Ochodaeidae, Geotrupidae, and Bolboceratidae).

General description 7

Scarabaeidae (Scarab Beetles)
This a large family of beetles, ranging in size from small to very large. They are usually black with a heavy carapace, and powerfully built. Many of these beetles display little interest in flowers, preferring to roam across the ground and hunt for other insect prey. Some of them are attracted to dung, which is shaped into a ball and rolled along the ground. This is deposited in a suitable hole, where the eggs are laid. Only one subfamily will be described, because the Scarab beetles in this group are more likely to visit flowers. Cetonniae (Flower Scarab Beetles): These are medium-sized beetles, somewhat round and flattened in shape. They are variably colored, sometimes iridescent green, black, or with brown and yellow patterns. The antennae are short and stout, like other Scarab beetles. The adults often appear on flowers, feeding on pollen, if not the flowers themselves. The larvae feed on plant roots, rotting wood, and decaying organic material in the ground.
