The Yellow Mealworm Beetle is a black darkling beetle whose larva, the mealworm, is one of the most widely recognized insects in the world — commercially raised by the millions as reptile and bird food. Adults are nocturnal, found in grain stores and under debris. Mealworms are now being studied as a sustainable protein source for human food.
