So I had a good amount of giant mealworms pupate....around 90 beetles. Everything I have read about these guys says that they can't pupate and even if they do the beetles don't do well and are sterile. Well I decided to try my luck..... All 90 something beetles survied. They have been mating and when I was cleaning bins I saw whole lot of baby worms. Has anyone else had success and what are the odds that these won't just turn out to be normal sized worms? I have a picture of a normal mealworm beetle next to one of the "giant" beetles for a size comparison.
