The energy they would use to pupate is instead channeled into making them grow 150% larger in length and width. You can also attempt to re-create this by keeping medium or large mealworms at a high temperature (high 80s) for 6 to 8 weeks. Increasing the daylight hours to a minimum of 14 hours will also enhance the effect. They will grow larger rather than pupate when conditions are safer ecologically.
If you prefer a worm that has not been altered in any way to force growth, then our standard mealworms are a perfect choice.
