The western pine beetle is an aggressive dark beetle that attacks and can kill ponderosa and coulter pines that are greater than 6 inches in diameter. The bugs eat the inner bark, while also transporting a fungus into the water-conducting wood to effectively clog the system and kill the tree.
Beetles are eaten by predators such as wasps, spiders, ants, mice, rats, moles shrews, salamanders, frogs, toads, birds, skunks and other beetles. In order to avoid being eaten, beetles run or hide in a tunnel when they are still larvae. A number of beetles have hard shells and can bite when defendi
Bark beetles kill pine trees by keeping nutrients from traveling from leaves to the rest of the tree and by keeping water from coming upward from the root systems to the leaves. Dehydration and malnutrition combine to damage and kill the trees in which these beetles establish colonies.
The diet of water beetles varies greatly due to the fact that there are close to 400,000 beetle species around the world. In North America, nearly 5,000 species of beetles live in water for at least part of their life cycles.
The aye-aye is a lemur that eats beetles. It uses long, thin fingers and sharp teeth to gnaw through tree bark to find beetles, insect larvae, nuts, seeds and fungi. The yellow-naped woodpecker catches flying beetles in midair and forages for them in the underbrush. The panther chameleon, gecko and
Black beetles eat grubs, caterpillars, fly maggots and pupae, aphids, weevils, earthworms, snails, slugs and other soft-bodied creatures. They also eat other species of beetles if they are small enough. This specific type of beetle is also called the Common Black Ground Beetle.
Pine borers are beetles whose larvae tunnel beneath the bark of conifers, causing damage. The most aggressive species belong to the genus Dendroctonus, and they are serious pests to forestry.
Christmas beetles eat eucalyptus leaves. When found in large populations, they can clean out entire trees. The Christmas beetle larvae eat grass roots.
Beetles live in different habitats all around the world. There are more than 300,000 recognized species of beetles as of 2014.
Certain species of beetles do have powerful jaws that bite. Other species such as the Blister beetle can produce a harmful chemical that will sting. Carpet beetles do not bite, but they can leave bite-like marks from their larvae which have fine, prickly hairs that impale into human skin.
