Scolytinae is a subfamily of beetles commonly known as bark beetles. They belong to the family Curculionidae and are primarily known for their role in the ecosystem as decomposers. These small insects typically bore into the bark of trees, where they lay their eggs and feed on the inner bark and wood. Bark beetles can have significant impacts on forest health, especially when populations become too large. Some species are known to transmit diseases to trees, leading to widespread tree mortality. Understanding the behavior and ecology of Scolytinae is essential for managing forest ecosystems and mitigating their effects on timber resources.
