Scolytidae, commonly known as bark beetles, are a family of small beetles that primarily infest trees. They are known for their role in the ecosystem, as they help decompose dead wood and recycle nutrients. Bark beetles typically bore into the bark of trees, where they lay their eggs and feed on the inner bark and wood. These beetles can be both beneficial and harmful. While they contribute to forest health by breaking down dead trees, some species can cause significant damage to living trees, leading to tree mortality. This is particularly concerning in forests affected by stressors like drought or disease, where bark beetle populations can explode, impacting forestry and ecosystems.
