Dicronorhina

Dicronorhina is a small genus of fairly large sub-Saharan flower chafers; the name has frequently been misspelled (as Dicronorrhina and Dicranorrhina) following misspellings and unjustified replacement naming in 1841 and 1842.[1]

Description

The species of the genus Dicronorhina 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.

gollark: I was looking at getting a GT 730 as a nearly-bare-minimum video output card for my server, should it work for *that* at least (under noveau, the open-source drivers, however you spell that)?
gollark: Also their high prices.
gollark: There's the famous image of Linus Torvalds showing them the number 4 in binary on his fingers.
