Hercules beetle (likely female)
Dynastes hercules
- Order & Family
- Coleoptera; Scarabaeidae (Dynastinae)
- Size
- Adults commonly measure 5–8 cm (2–3.2 in); males can exceed 15 cm including horns, while females lack prominent horns.
Natural Habitat
Tropical forests of Central and South America and the Caribbean, especially humid lowland woodland. Adults are often attracted to lights at night.
Diet & Feeding
Larvae feed on decaying wood and leaf litter. Adults mainly consume fruit, tree sap, and juices from ripe or fermenting vegetation.
Behavior Patterns
Primarily nocturnal; adults fly to lights and use their horns for male contests over mates or feeding sites. Larvae develop in rotting logs over many months to years before pupating.
Risks & Benefits
Harmless to people, though adults may pinch if handled. Larvae help decompose wood and recycle nutrients; this identification is tentative because the image could also show a related rhinoceros beetle.
