Megasoma punctulatus (M. punctulatum on Bugguide.net) is the US cousin to the giant Elephant Beetles that range from Mexico to South America. The specimen in the photo is from our first captive generation and measures 40 millimeters. With access to a quality substrate on a consistent basis this desert species has the potential to grow much larger in captivity. Care for them is the same as with other rhino beetle larvae (like Dynastes). They feed on decaying wood from hardwood trees. We sell both a hardwood substrate product, and then also a deco cube cage for beetle larvae in the related items section below.
