Natural Habitat

Tropical and subtropical forests of Central and northern South America and some Caribbean islands, especially humid forest floors and decaying logs.

Diet & Feeding

Larvae feed on decaying wood and organic plant matter. Adults mainly consume fruit, sap, and other sugary plant fluids.

Behavior Patterns

Mostly nocturnal and attracted to lights; adults fly seasonally, while larvae develop for many months to years in rotting wood. Males use their horns in contests, whereas females are hornless.

Risks & Benefits

Harmless to people and not venomous; its spiny legs can grip or scratch if handled. Larvae help decompose wood and recycle nutrients, and adults contribute modestly to forest food webs and pollination.
