The Eacus Golofa Beetle is a long-horned rhinoceros beetle native to the Andes, ranging from Colombia down to Bolivia. A medium-sized species at roughly 40 to 60mm in length, its standout feature is the male's slender head horn and thorax horn, which curve dramatically toward each other. This gives it a silhouette quite different from beetles with straight horns, making it a distinctive and collectible species among enthusiasts. Domestic keeping records are still relatively limited, so there's an element of discovery in raising one and documenting your own observations along the way. For that reason, it's best suited to keepers who already have some beetle-rearing experience rather than absolute beginners.

Eacus Golofa Beetle key facts
- Care level
- Intermediate
- Lifespan
- Adults 4-7 months
- Size
- 40-60 mm
- Diet
- Beetle jelly; tree sap
- Temperature & Humidity
- 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.
- Breeding & Egg-laying
- 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.
- Cohabitation
- 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.
- Lifespan & Rearing Period
- 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.
- Health & Notes
- 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.
About Eacus Golofa Beetle
A 40–60mm rhinoceros beetle from the Andes (Colombia to Bolivia), known for the male's dramatically curved, facing head and thorax horns. A collectible species best suited to intermediate keepers.
7 things to know before welcoming a Eacus Golofa Beetle
1Horns That Face Each Other
Males grow a slender head horn and thorax horn that curve dramatically toward each other, giving this beetle a shape unlike species with straight horns. It's this striking silhouette that draws collectors to the species.
2Native to the Andes
This beetle ranges along the Andes mountains from Colombia down to Bolivia. Since domestic rearing records are still limited, keeping one involves a certain amount of observation and trial as you go.
3Suited to Intermediate Keepers
This species is generally considered suitable for intermediate keepers rather than complete beginners. It's a good idea to have some prior experience with basic beetle care — temperature and humidity control, substrate changes, and the like — before bringing one home.
4Telling Males From Females
The elaborate head and thorax horns are a male trait — females have little to no horn development. This makes it straightforward to tell the sexes apart when choosing which to bring home.
5Feeding Adults
Like most beetles, adults are typically fed insect jelly as their staple diet. Provide a feeding dish with good footing to prevent them tipping over, and replace the jelly regularly.
6Setting Up for the Larval Stage
Like other rhinoceros beetles, this species passes through a larval stage before emerging as an adult, so maintaining good substrate condition, humidity, and airflow supports healthy development. Avoid sudden environmental changes and check on the larvae regularly.
7Preparing Before You Bring One Home
Because domestic care information for this species is still limited, it helps to have your enclosure, substrate, and temperature setup ready before you bring one home, and to go in expecting to keep your own notes as you learn what works.
Frequently asked questions about Eacus Golofa Beetle
- Q.How big does the Eacus Golofa Beetle get?
- A.Adults reach roughly 40 to 60mm in length, making this a medium-sized beetle. Males look more imposing thanks to their long horns, but the body itself falls within this size range.
- Q.How long do they live?
- A.Detailed lifespan data hasn't been well established for this species, since domestic rearing records are still limited. Individual variation can be significant, so it's best to keep an eye on your beetle's condition day to day.
- Q.Is this a good beetle for beginners?
- A.This species is generally rated as suited to intermediate keepers rather than complete beginners. It's a better fit for someone who already has some hands-on beetle-keeping experience.
- Q.Do both males and females have horns?
- A.No — the pronounced head and thorax horns are a male characteristic. Females have little to no horn development, which makes the sexes easy to tell apart at a glance.
- Q.Is this species subject to any CITES restrictions?
- A.The Eacus Golofa Beetle is not listed under CITES.
