Mecynorhina polyphemus (Fabricius, 1781)

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]
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. Females are typically 35–55 mm, while males range from 35 to 80 mm.[2]
