Why do bess beetles bury themselves?

Bess beetles bury themselves primarily for protection and to create a suitable environment for their larvae. By excavating decaying wood, they create a safe, dark habitat that helps shield them from predators and environmental hazards. Additionally, the buried wood serves as a food source for both adult beetles and their offspring, ensuring access to nutrients as they develop. This behavior also facilitates the decomposition process, contributing to nutrient cycling in their ecosystem.
