Earthworms and snails are common prey for carnivorous beetles. Ants are another common food source for beetles, and there are over 1,000 different kinds of beetles that are parasitic, predatory or commensal, meaning they benefit from a relationship with another species while the other species is unaffected, in ant communities. Some beetles are ectoparasitic, meaning they live on the skin of a mammalian host and feed on skin tissue and secretions.
Honey bees are another food source for parasitic beetles, such as the small hive beetle. The larvae infiltrate the beehive and destroy the comb by tunneling through towards the honey.
