Explanation of Names

Author is Leach, 1815, the subfamily named for Old World genus Cetonia (e.g., Cetonia aurata). Origin of name is obscure--The Century Dictionary (1) does not list an etymology. One Internet source says that ceton is Gaulish for woods, forest. Ceton (or Seton) is a surname as well, so perhaps this is an eponym. Or perhaps there is a connection with Latinized Greek cetus, whale. (Editorial note: OED needs to be checked.)

Identification

Characteristics (2), (3), (Generic Guide to New World Scarabs--key)

body shape usually somewhat flattened

none have horns

Antennal insertion is visible from above--clypeus with sides constricted in the middle, just in front of the eyes

mandibles and labrum hidden by clypeus

pygidium exposed

tarsal claws simple (not forked), and more-or-less equal in size

Food

Many found on flowers, where feed on pollen.

Life Cycle

Larvae feed on roots, organic material in soil, or decaying wood in trees. Some are associated with ant nests (myrmecophiles), and adults may be found there as well.
