Dicronorrhina is a small genus of fairly large sub-Saharan flower chafers; the name has frequently been misspelled (as Dicranorrhina and Dicronorhina) following unjustified spelling changes in 1841 and 1842.[1]
Description
The species of the genus Dicronorrhina reach about 40–60 millimetres (1.6–2.4 in) in length. Their basic body colour is metallic green, with white stripes in some species. The male has a "T"-shaped, flat horn in the forehead. The larvae live in the soil on decaying vegetable material. The development will take 8–9 months, and the adult beetles can live 3–4 months, so that there is one generation per year.
Distribution
This genus is widespread in Africa south of the Sahara.
