Lucanus cervus

Impressive Beetle with Antlers

The stag beetle is the largest beetle in Central Europe. Only the males have “antlers.” The membranous hind wings are folded beneath the hard elytra. Despite their size, they are capable of flight, though they are rather poor fliers.

Did you know?

The horn-like structures on the males have developed from the upper jaw. They use these pincers in combat to pin their opponents down.
