What is a "stag beetle"?

A stag beetle is a large and charismatic insect belonging to the family Lucanidae. Known for its impressive size and distinct mandibles resembling the antlers of a stag, this beetle has a striking appearance. Stag beetles are often considered iconic insects due to their unique features and fascinating behavior. The males, with their oversized mandibles, use them to compete for mates and establish dominance. Despite their intimidating appearance, stag beetles are generally harmless to humans, as they primarily feed on decaying wood and tree sap.
