Golofa eacus
A Golofa distributed along the Andes from Colombia to Bolivia. It is a medium species of 4-6 cm, the male carrying a slender head horn and thoracic horn. Little husbandry information circulates in Japan.
Golofa eacus was described by Burmeister in 1847; it is a South American species of 4-6 cm. GBIF holds most records from Colombia, followed by Ecuador, Peru and Bolivia, which traces the Andes. As in the rest of the genus the male carries one horn on the head and one on the prothorax, the two curving toward each other, and the long forelegs are behind the alternative Japanese name for the genus. The BE-KUWA FY2025 edition carries no captive record for this species in its Golofa section, and little husbandry information circulates in Japan. Anyone attempting it has to follow the method documented for the congener Golofa claviger: a substrate egg-laying set and larvae grown on rhinoceros-beetle substrate.

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.

The congener Golofa claviger is kept at about 23-25C, and since most of the genus is montane, avoid the warm regime used for lowland species.
Egg-laying uses the same substrate set as for other rhinoceros beetles. For the congener Golofa claviger, mixing black soil into the substrate is said to raise the number of eggs; larvae are grown on rhinoceros-beetle substrate in a final bottle of 1400-1500 ml, and the larval period runs 10-12 months, sometimes two years. No measured figures have been published for this species.
Males shove each other with their thoracic horns, so keep them singly and pair them only for the short time needed to see mating. Adults of the congener Golofa claviger are short-lived, and keepers are advised to pair beetles as soon as they start feeding.
Neither adult lifespan nor larval period has been published for this species. The congener Golofa claviger is given as two to six months as an adult with a larval period of 10-12 months, which means allowing about eighteen months for a generation.
A cramped pupal cell leaves the horns bent on emergence, so give the final instar a roomy container. Importing live beetles requires the species identification certificate demanded for live Scarabaeoidea.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Eacus Golofa Beetle is Adults 4-7 months. With proper care and nutrition, they can live a long and healthy life.
Eacus Golofa Beetle typically reaches 40-60 mm as an adult. Size may vary depending on care conditions and individual genetics.
Eacus Golofa Beetle feeds on: Beetle jelly; tree sap. Aim for a balanced diet with appropriate feeding frequency.
