Giant Stag Beetle

description Giant Stag Beetle Overview

The giant stag beetle (*Lucanus elaphus*) is a large insect native to the eastern United States and the largest stag beetle species in North America. Males are distinguished by their greatly elongated, branched mandibles that resemble antlers, which they use to compete for mates. Females have much smaller, but strongly serrated mandibles. Both sexes rely on decaying hardwood logs for larval development, playing a specific ecological role in forest decomposition.
