Reddish-Brown Stag Beetle

Lucanus capreolus, Reddish-Brown Stag Beetle photo`

Family: Lucanidae

Subfamily: Lucaninae

Length: 23 - 37 mm


When confronted by people, the male beetles may rear back their heads and open their mandibles, but actually these pincers are capable of little more than a mild nip to a human.

Male Reddish-Brown Stag Beetles use their mandibles in fights with other males over females.

The mandibles of females are directed forward like those of the males, but are much smaller. Some "minor males" also have smaller mandibles.

Adults of Lucanus capreolus are nocturnal and feed on tree sap. They are also attracted to lights. The larvae feed on the decaying wood of tree stumps and fallen logs.

The map near the bottom of this page shows the states and one province with records of Lucanus capreolus in blue-green.

Photo data: 15 July 2006. Rurdaldale, Upshur County, West Virginia.
