Some beetles are highly specialised in their diet; for example, the Colorado potato beetle, Leptinotarsa decemlineata, almost exclusively colonizes plants of the potato family (Solanaceae). Species such as longhorn beetles, leaf beetles and weevils feed only a single plant and are thus very host-specific. Hellgrammite . There is a cavity under the elytra, where the air is stored. Many species of the family Staphylinidae such as rove beetles and ground beetles are carnivorous and feed on other arthropods like snails and earthworms.

Spiracles (openings to the respiratory system) are placed on the top of the abdomen and enter the cavity. A growing body of research proves how important terrestrial insects are in trout diet, particularly on small freestone streams. In nature, diving beetles are scavenger-predators. The behavior of this diving beetle has been compared to a scuba diver, since it carries with it a bubble of air as it dives down into the water. The Cape foxes diet entails rodents (particularly the gerbil mouse and pygmy mouse), arthropods (beetles, termites, and scorpions), rabbits, and small reptiles, and will occasionally consume wild fruits.
