I have now 7 Pasimachus elongatus beetles and there is definately some beetle sex going on. It looks really neat in a sick and twisted kind of way. Anyways, Im wondering what would be a good substrate to keep these on in the hopes of some "mealworms" getting laid. I don't really know too much about keeping beetles, but they have sure been eating and thriving on moist coco bedding. Beetleman where are ya?
