As an entomologist with a focus on insect ecology, I can provide you with information regarding the impact of stag beetles on their environment.

Stag beetles, scientifically known as Lucanus, are typically not considered harmful to humans or the environment. They are known for their impressive mandibles, which are used primarily for mating competition and digging, rather than for feeding on plants or causing structural damage. In fact, these beetles are beneficial as they act as decomposers, breaking down dead wood and contributing to the nutrient cycle in forests.

However, there are a few considerations to keep in mind. In some cases, if a stag beetle burrows into a wooden structure, it could potentially cause minor damage, but this is quite rare and not considered a significant threat. Additionally, the larvae of these beetles feed on decaying wood, so they are not harmful to living plants.

It's also important to note that stag beetles are often considered a sign of a healthy ecosystem due to their role in decomposition and their sensitivity to habitat disruption. Therefore, they are often protected by conservation efforts.

In conclusion, stag beetles are not harmful and are generally seen as a positive presence in the environment.
