What special adaptations does bark beetles have?

Bark beetles possess several special adaptations that enable them to thrive in their environments. They have strong mandibles designed for boring into tree bark, allowing them to access the inner phloem layer for feeding. Additionally, they produce pheromones to communicate and attract mates, as well as to signal other beetles to join in attacking a tree. Some species also harbor symbiotic fungi in their bodies, which help them break down wood fibers and provide additional nutrients.
