Insects and other arthropods are perhaps the most significant natural enemy of trees. They help keep plant populations in check by feeding on the unripe seeds and leaves, as well as on the mature foliage. In fact, these insects alone disseminate about 80% of plant seeds every year.
Some species feed on the sap and bark of living plants, causing severe damage that can lead to death if left unchecked. They may enter the tree through wounds or holes bored into its trunk, branches, or foliage by other arthropods such as moles, shrews or bats. Many munch on the leaves and branches until the branch or tree becomes fragile. Some insects come out in specific seasons like summer or fall.
