What is a "spruce bark beetle"?

A spruce bark beetle is a small but destructive beetle species that primarily infests and damages spruce trees. These beetles bore through the bark of spruce trees, creating tunnels where they lay their eggs. The larvae then feed on the inner bark, disrupting the tree's ability to transport water and nutrients, ultimately leading to the decline and death of the affected spruce trees. The infestation of spruce bark beetles can have significant impacts on forest ecosystems and timber industries.
