Definition
The family Lucanidae encompasses all species of stag beetles, characterized primarily by the enlarged mandibles in males. These mandibles, resembling deer antlers, are used for wrestling rivals during mating season. These beetles are generally large, with some species reaching impressive sizes. Larvae develop within decaying wood, contributing to decomposition and nutrient cycling. The family exhibits a global distribution, with diverse species found across various continents. Conservation efforts often focus on preserving habitats suitable for larval development.
