During which general time frame do adult stag beetles typically appear and become active above ground?

Answer

During the warm summer months

The visibility of adult stag beetles is directly linked to seasonal temperature fluctuations, as they are primarily active when the weather is warm. Specifically, adult specimens generally emerge and become active during the warm summer months. This activity involves flying, often near sources of light, and searching for mates or suitable locations, such as decaying wood, in which to deposit their eggs to continue the life cycle. It is important to distinguish this observation window from the larval development period, which occurs hidden away year-round within rotting timber.
