Cetoniinae Leach, 1815
Explanation of Names
The subfamily is named for Old World genus Cetonia (e.g., Cetonia aurata). Origin of name is obscure--The Century Dictionary (1) does not list an etymology, stating simply that it is New Latin (NL). Perhaps there is a connection with Greek ketos (κετος), whale. (Leach also described many marine species, so this is plausible.)
Other possibilities: 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.
Characteristics (2), (3), (Generic Guide to New World Scarabs--key)
body shape usually somewhat flattened
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
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.
