While growing they shed their skin, which contains chitin. This chitin ends up in the fertilizer.
Cycle stages
Mealworms go through a life cycle consisting of four stages: egg, larva (mealworm), pupa, and adult beetle. The larvae stage is the end product at the farm.
Beetle
Beetle lay the eggs which hatch into the mealworm larva. They get the same feed as the mealworm but get their water from carrots. When eggs production stops the beetles are processed to be used as birdfeed.
