Here are a couple pictures I took of specimens from my collection representing the four species in the genus Chrysina that are native to the US. The larvae develop in decaying wood and rich organic soil.
The species in clockwise order from the upper left are: Chrysina woodi (Horn), Chrysina lecontei (Horn), Chrysina gloriosa (LeConte), and Chrysina beyeri (Skinner). Chrysina woodi is found in Texas and New Mexico, the rest are found here in Arizona and the desert southwest.
So, do you like black or white better?
