Stag beetles

1 hose beetles arc typically large, smooth, and black or reddish brown. Males arc larger than females and have greatly enlarged mandibles that may be lined with prominent teeth. These powerful mandibles are used in male-to-male combat over females and arc designed to fit around the edges of a rival's pronotum, with the victor Hipping its rival over. Adults are mainly nocturnal and either do not feed or take fluids (plant sap, nectar, or fruit juice).

• LIFE CYCLE The female lays her eggs on decaying tree stumps, roots, or logs. Stag beetle larvae may take several years to complete their development. The larvae pupate inside a cell that is composed of chewed wood fibers.

• OCCURRENCE Worldwide. In deciduous woodland and forests.
