Golofa claviger
A South American Golofa also called the rhomboid-horned beetle in Japan, after the shape of its thoracic horn. Peruvian stock is what mostly circulates now, and it is regarded as an easy species to breed on ordinary substrate.
Golofa claviger was described by Linnaeus in 1771. Its range is given as Peru and Ecuador, and it measures 40-65 mm in males and 35-55 mm in females. The thoracic horn looks rhomboid, which is behind one of its Japanese names, and Peruvian stock is what mostly circulates today. Its habits in the wild are little studied, though it has been reported as a pest of oil palm in northern Brazil. Keep it at around 23-25C and use the same substrate egg-laying set as for other rhinoceros beetles; plain rhinoceros-beetle substrate works, but mixing in black soil is said to raise the number of eggs. Larvae are grown on the same substrate with a final bottle of 1400-1500 ml, and the larval period runs 10-12 months, occasionally two years. The BE-KUWA FY2025 edition lists a captive record of 67.7 mm.

Captive record (♂)
67.7 mm
Record source: BE-KUWA 2025 edition (Golofa claviger, nominate form, captive 67.7 mm, 謝孟廷 2020; projected maximum 88 mm)
Notable localities
The record is registered for the nominate form. At 67.7 mm it is well short of the 88 mm projected maximum. The rhinoceros-beetle table carries no wild-record column, so no wild figure is given.

Plant Protection Act: When importing live specimens of Scarabaeoidea (including rhinoceros beetles, stag beetles, flower beetles, etc.), a species identification certificate issued by the exporting country government agency or equivalent must be attached in accordance with the Invasive Species Act (import ports are limited to Narita, Chubu, Kansai, Fukuoka, and Kagoshima airports). This species itself is not a designated invasive species, and import is possible upon submission of the certificate.

Keep it at about 23-25C. For humidity, hold the substrate just damp enough to clump when squeezed.
Egg-laying uses the standard substrate set. Plain rhinoceros-beetle substrate works, but mixing in black soil is said to raise the number of eggs. Larvae do well on the same substrate and are not difficult provided substrate changes are handled carefully. Allow a final bottle of 1400-1500 ml; the larval period is 10-12 months and sometimes two years.
Males shove each other with their thoracic horns, so keep them singly and pair them only for the short time needed to see mating. Because adults are short-lived, keepers of Golofa claviger are advised to pair beetles as soon as they start feeding.
Adults live only two to six months. Treat the start of feeding as the sign of maturity and pair the beetles soon after they become active. With a larval period of 10-12 months, allow about eighteen months for one generation.
A bottle that is too small leaves the horns bent when the beetle emerges, so give the final instar a roomy container. Importing live beetles requires the species identification certificate demanded for live Scarabaeoidea.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The ideal temperature for Claviger Golofa Beetle is 23〜25℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Claviger Golofa Beetle is Adults 3-6 months. With proper care and nutrition, they can live a long and healthy life.
Claviger Golofa Beetle typically reaches Males 40-65 mm / females 35-55 mm (stock on the market runs about 43-60 mm for males and 40-50 mm for females) as an adult. Size may vary depending on care conditions and individual genetics.
Claviger Golofa Beetle feeds on: Beetle jelly; tree sap. Aim for a balanced diet with appropriate feeding frequency.
