Mealworms are the larvae of the Tenebrio molitar beetle. Their diet is vegetarian which means they are safe to feed to animals and birds without passing on the potentially fatal diseases which may be present in offal-fed larvae such as maggots. They are a clean odourless and relatively inexpensive livefood, rich in protein and easy to store. Popular as livefood for many species of aviary and garden birds.
