A friendly guide, not veterinary advice. For anything about your pet's health, ask your vet.
At a glance the quick version
Body length (without horn) 5.0-8.5 cm; with horn, males up to 17.3 cm.
Adults live 3-6 months in captivity, occasionally up to 1 year.
Looks how to spot one
Exoskeleton
Males have two long horns, one on the head and one on the thorax, used for fighting. The elytra (wing cases) are olive-green to yellow with black spots, and they darken in high humidity. Females are entirely black with punctured elytra and lack horns.1
Personality what they are like
Males are territorial and will fight other males, but they are not aggressive toward humans. They are nocturnal and spend most of the day burrowed. Handling should be gentle and limited, as they are better as display pets.13
Daily activity how busy a day looks
Low activity needs. Provide a secure enclosure with 7-10 cm of substrate for burrowing, plus branches and bark for climbing. They are most active at night.23
Grooming and care the hands-on bits
Minimal grooming. Keep the enclosure clean and remove uneaten fruit to prevent mould. Maintain moderate humidity and good ventilation.4
Home where they are happiest
A terrarium with at least 7-10 cm of moist sphagnum moss or soil mixture for burrowing. Provide branches and bark for climbing. Keep at room temperature (around 25°C) and moderate humidity. Males must be housed separately to avoid fighting.25
Food basics what goes in the bowl
Adults eat soft, sweet fruits such as bananas, apples, mangoes, peaches, and melons. Avoid citrus fruits as they can upset the beetle's gut. Commercial beetle jelly is also suitable. Larvae feed on rotting wood.41
Company who they like around
Solitary. Males are aggressive toward each other and must be housed alone. Multiple females can be kept together with one male. They do not need social interaction with humans.25
The story where it all began
The Hercules beetle has been kept by insect hobbyists for decades, prized for its enormous size and striking horns. It is one of the most popular rhinoceros beetles in the pet trade. Wild populations are found in tropical forests from Mexico to Bolivia.14

Owner questions the things everyone asks
How often should I feed my Hercules Beetle?
Feed your adult Hercules Beetle fresh fruit every day or every other day, removing any uneaten pieces to prevent mould. Larvae eat rotting wood, which should be available continuously. For exact amounts, check the food label or ask your exotic-pet vet.41
What does a Hercules Beetle eat, and what should it never eat?
Adults enjoy soft, sweet fruits like bananas, apples, mangoes, peaches, and melons, as well as commercial beetle jelly. Never give citrus fruits, as they can upset the beetle's gut. Larvae feed on rotting wood.41
How much space does a Hercules Beetle need?
A terrarium with at least 7, 10 cm of moist substrate for burrowing is needed, plus branches and bark for climbing. Males must be housed alone to avoid fighting, so provide a secure enclosure that suits one beetle.25
What temperature, light or water does a Hercules Beetle need?
Keep the enclosure at room temperature, around 25°C, with moderate humidity and good ventilation. They are nocturnal and do not need special lighting. Provide moisture through the substrate and a shallow water dish if needed.254
How often should I clean a Hercules Beetle's home?
Remove uneaten fruit daily to prevent mould, and clean the entire enclosure every few weeks or as needed. Maintain moderate humidity and good ventilation for a healthy habitat.4
Can a Hercules Beetle live with others?
Hercules Beetles are solitary. Males are aggressive toward each other and must be housed alone. Multiple females can be kept together with one male, but they do not need social interaction with humans.25
How long does a Hercules Beetle live?
The lifespan varies depending on species and care; for specific details, consult a good breeder or an exotic-pet vet. They are generally short-lived as adults, with larvae taking months to develop.
Can I handle a Hercules Beetle?
Handling should be gentle and limited, as they are better as display pets. They are not aggressive toward humans but are nocturnal and prefer to burrow. Always handle with care to avoid stress.13
