Mealworms are the larvae of yellow mealworm beetles (Tenebrio molitor), a species of darkling beetle, and can reach lengths of 4 -5 cm, making them some of the largest insect larvae. They are typically used as a food source for reptiles, fish and birds. Larvae hatch from eggs and are the second stage in the lives of insects that undergo complete metamorphosis.
