What Do Beetles Eat?
1. Decaying Matter
In general, many beetle species consume decaying organic matters for survival. Examples of these things are decaying plant leaves, and wood, animal dung, and even dead animal remain and debris. Mildew beetles feed on fungus.
Species of the Carrion beetles, Clown beetles, and the Scarab beetles are known to have this kind of diet.
2. Plants
There are also other beetle species that feed on vegetation and as such are considered to be pests. These insects like to consume the leaves and make holes to them, resulting in their discoloration and eventually death. Examples of these beetles are the Cottonwood Leaf beetles and the Elm Leaf beetles.
Other species of beetles residing in aquatic environments also feed on algae Aside from the leaves, there are also species of beetles that are capable of destroying and digesting the wood of trees. And like the beetles that feed on leaves, these beetles are also considered as pests because they bore through the stem and roots of woody plants, which eventually may result in the plant’s death. Other beetles like the rice weevils and primitive weevils feed on other plant parts like rice and other grains, and pollen grains of plants (respectively).
3. Household Materials
Powder post beetles and Longhorned beetles feed on wood materials found in home structures such as beams, wooden artifacts, & furnitures and could cause some severe damage to homes.
4. Insects
Aside from being vegetarian, some beetles also practice carnivory and feed on beetles and other insects. One famous example is the Lady beetles which feed on caterpillars

5. Other Animals
Interestingly, a species of water beetles known as the Predaceous diving beetle Dysticus sp. Is living up to its name because it acts as a predator to other water bugs, amphibians, and some snakes
Water beetles eat tadpoles Another awesome example is the adult whirligig beetles and their larvae. These beetles are known to be carnivorous and feed on aquatic insects and crustaceans.
Coleoptera is the largest order of the class of insects. In fact, scientists believe that more species of insects under this order are yet to be identified and be added to the 400,000 known species.
Who knows they might discover beetle species that eat more bizarre things than those already mentioned?
