A giant rhino beetle Megasoma elephas elephas is magnificent species from neotropical ecozone which lives in tropical forests from Southern Mexico to Venezuela. The males are one of the largest beetles in the world reaching over 13 cm in size. Considering the fact that the beetle's elytron is also quite wide, the adult beetles look and feel (when handled:) massive. In nature the adult beetles feed on sweet sap from trees and ripe fruits, whereas the larvae are found in decayed organic plant material, such as rotten wood.
Although many breeders suggest feeding the female of a rhino beetle for about 2 weeks before mating, I did not see any significant difference in number of eggs laid between "pre-fed" and fresh females, especially if you are going to have only one pair of adults in the breeding box. The egg laying setup is similar to any rhino beetle setup; the potting soil is mixed with some mulched decayed leaves and wood and the lower layer is compressed with a hand. A few bigger chunks of wood should be placed at the top of the soil so the beetle could grab if it flips over. The eggs and the fresh larvae can be collected after about 1.5-2 months. The female may lay somewhere between 30 and 60 eggs, but sometimes more. The most of the eggs will be laid in the compressed bottom layer of the box.
