is closely related to the enormous Hercules beetle (Dynastes hercules)
of Central America, which can reach lengths of 17 cm (6.5 inches).
D. tityus measures some 6 cm in length and occurs over a wide area
of the eastern United States, ranging as far north as New Jersey, and as

The larvae develop in the compost of dead trees, particularly deciduous
