The Royal Goliath Beetle is a large flower beetle native to West Africa, prized for its striking white elytra marked with black patterns and, in males, a distinctive Y-shaped black horn. Adults show notable size variation between sexes — males reach 50 to 115mm while females grow to 56 to 82mm — giving the species real visual presence. Because the carnivorous larvae need a high-protein diet and often face mortality during pupation, breeding this species successfully is considered an advanced-level challenge. Adults can live over a year in captivity, rewarding keepers who want a long-term relationship with a truly impressive beetle.

About Royal Goliath Beetle
The Royal Goliath Beetle is a large West African flower beetle known for its black-patterned white elytra and the male's Y-shaped horn. Larvae are carnivorous, making this an advanced-level species; adults can live over a year.
7 things to know before welcoming a Royal Goliath Beetle
1Advanced-Level Care
The Royal Goliath Beetle is considered a species best suited to experienced keepers. Successfully managing larval feeding and pupation requires specialized knowledge, so it's best to build experience with insect keeping before taking one on.
2Carnivorous Larvae Diet
The larvae of this species are carnivorous, so standard flower-beetle larval substrate alone isn't enough. Providing a high-protein food source is essential and is one of the trickiest parts of raising this beetle.
3Delicate Pupation Stage
The transition from larva to pupa is a particularly sensitive stage, and mortality during pupation is not uncommon. This is one of the main reasons breeding this species across generations is considered difficult.
4Male Horn and Size Gap
Adult males develop a distinctive Y-shaped black horn, and males (50-115mm) tend to grow noticeably larger than females (56-82mm). The white elytra marked with black patterns are another signature feature of the species.
5Adults Live Over a Year
Adults can live more than a year in captivity, making them one of the longer-lived beetles to keep. It's worth setting up an environment suited to a long-term relationship with your beetle.
6West African Origins
This large flower beetle is native to West Africa, an environment quite different from Japan's climate. Approximating the temperature and humidity of its native habitat is key to successful care.
7Before You Bring One Home
The striking appearance and collectible appeal make this species popular, but it demands real effort in larval feeding and pupation care. Research proper husbandry thoroughly and prepare accordingly before bringing one home.
