The scarab beetle family is very large, with breathtaking variety—and often great beauty. Although many are black, brownish, or drab, many scarabs are colorful, some with iridescent greens and other colors, others looking as if they were covered with shiny enamel paint. They are oval or elongated, stout, usually with rounded backs, and have clubbed antennae with segments that can press tightly together or can be fanned open like leaves. In several species, the males (sometimes females, too) have pointy horns. Several species are quite large.
The larvae of most scarab beetles are whitish, C-shaped grubs that live underground or in other protected places. The heads are often brownish or black, and they have three pairs of legs.
