Range:  southeastern US
Size:  20 - 28 mm

Gymnetis caseyi is a strikingly patterned member of the cetoniine scarab beetle tribe Gymnetini.  This species usually measures about 20 mm in length.  The American tropics and subtropics contain a wealth of Gymnetis species, but G. caseyi is the only one that occurs north of Mexico.

Gymnetis is one of a number of cetoniine scarabs which possess a fine surface layer which covers the upper surface of their bodies.  It is extremely smooth to the touch, and is composed of many tiny, microscopic projections. Some of the large African cetoniines, such as Chelorrhina and Goliathus, also have this smooth layer covering the surface of their exoskeletons.

Gymnetis beetles are primarily associated with low and mid-elevation tropical rainforests.  They have been observed feeding on a variety of flowers, fruits, and tree sap.  The adults are diurnal, like most other beetles of the subfamily cetoniinae.  The larvae of most species feed on decaying wood, although a few are known to specialize in living within the nests of leaf-cutter ants (Atta spp.), where they apparently feed on detritus left by the ants.
