  Mealworms are the larva of the Darkling beetle. The mealworm is slightly hard, about a quarter of an inch to three quarters of an inch long. Once the mealworm turns into an adult, it is black and it is difficult to tell a male from a female beetle. Mealworms and the adult beetles live where there is plenty of decaying foliage, in rock crevasses, in logs, grain storage and animal burrows. The predators to mealworms include rodents, lizards, predatory beetles, birds and spiders.
