Mecynorhina polyphemus is a large scarab beetle of the subfamily Cetoniinae found in dense tropical African forests. It is a frequent feeder on fruits and sap flows from tree wounds. There are several varieties including M. polyphemus polyphemus, M. polyphemus confluens, and M. polyphemus rufuino. [1]

The larvae develop in decomposing log compost. The third instar constructs an ovoid cocoon for metamorphosis and attaches it to a solid surface. In captivity, the instar may attach the cocoon to a glass container wall allowing the opportunity to view the transformation.[1] [2]

Male and female are dimorphic. The female has a shiny surface texture, reflective prismatic coloration, and no horns. The male has horns and flat, velvety coloration.[1] Females are typically 35–55 mm, while males range from 35–80 mm.[3]

Common names include Polyphemus beetle, magnificent flower beetle, giant African fruit beetle.
