This superfamily includes some of the largest beetles extant today, including rhinoceros beetles, (Dynastinae), the Hercules beetle (Dynastes hercules) and Goliath beetles (Goliathus sp.).

Phanaeus, the rainbow scarabs, [1] is a genus of true dung beetles in the family Scarabaeidae (scarab beetles), ranging from the United States to northern Argentina, with the highest species richness in Mexico. [2] [3] Depending on species, they can inhabit a wide range of habitats, from tropical to temperate climates and deserts to rainforests.
These beetles are small scarab beetles, most less than 8 millimeters long. Many have small mandibles that are covered by a widened clypeus, the exoskeleton plate above the mouth. The feet are clawed. [1] This is a diverse subfamily with varied life strategies and habitat types. Many species are dung beetles, which collect and feed on animal dung.
Beetles are sometimes used as instruments: the Onabasulu of Papua New Guinea historically used the "hugu" weevil Rhynchophorus ferrugineus as a musical instrument by letting the human mouth serve as a variable resonance chamber for the wing vibrations of the live adult beetle.
