Do Megasoma species tend to surface or become seemingly lethargic before a molt? I have yet to actually witness a molt, but I've got one M punctulatus who has grown quite fat and firm in the body (head is still fairly small) who is hanging out on the surface of its substrate. The larva barely moved at all when picked up until I prodded its head, at which point it recoiled as expected. There was a good bit of frass in the substrate, so I went ahead and mixed it with new oak flake from BiC, and placed the larva into a hole, but it's back on the surface again this morning.
