The Figeater beetle is a large scarab beetle up to about 34 mm long, dull metallic green above with tan to brown margins on the wing covers and a short, horn-like bump on the face. The underside gleams with a brighter metallic shine than the matte top of the beetle.

Grubs live in compost, mulch, manure and other rotting plant matter for about a year, feeding on the decaying material rather than on living roots. Adults fly by day in warm months, feeding on nectar and soft ripe fruit such as figs, peaches and grapes, and occasionally damaging garden crops in the process.
