The Actaeon Beetle is a massive rhinoceros beetle from the tropical forests of South America, ranking among the heaviest species alongside the Elephant Beetle. Adults reach 50 to 135mm, and even the larvae grow to an impressive size long before pupation. Its sturdy build and imposing horn give it real presence in a collection. While its movements are calm, keeping a beetle this large demands generous enclosure space and careful management, which is why it's considered a species for experienced keepers. It suits anyone who wants to watch a South American giant develop over time and appreciate its substantial, powerful charm.

- Care level
- Advanced
- Lifespan
- Adult 3-6 months
- Size
- 50-135mm
- Temperature
- 22〜26℃
- Diet
- Insect jelly
- Housing
- Very large larvae require large containers
- Temperature & Humidity
- Keep the temperature at 22-26°C. As a rainforest species it dislikes dry conditions, so mist the substrate to keep it moist.
- Diet & Feeding
- Feed adults beetle jelly or banana. Adults live only about 3-6 months, so never let the jelly run out after emergence.
- Breeding & Egg-laying
- Prepare large amounts of leaf mold or fermented substrate for egg laying and larval rearing. The larval stage lasts 18-36 months, so patience is essential.

7 things to know before welcoming a Actaeon Beetle
1An Advanced-Level Species
The Actaeon Beetle is regarded as a species for experienced keepers. It needs consistent temperature and humidity control plus generous enclosure space throughout both the larval and adult stages. If you're new to beetle keeping, it's a good idea to build experience with a smaller species first.
2A Large 50-135mm Body
Adults range widely from 50 to 135mm, giving this species the presence of one of South America's largest beetles. Larger individuals need correspondingly larger enclosures, so it's worth securing adequate space before bringing one home.
3Larvae Grow Just as Large
Alongside the Elephant Beetle, this species is among the heaviest rhinoceros beetles, and its larvae grow remarkably large well before pupating. That means providing plenty of substrate and swapping it out regularly during the larval stage.
4Adult Lifespan of 3-6 Months
Once it reaches adulthood, this beetle typically lives for about 3 to 6 months. Since that window comes after a much longer larval stage, it's worth savoring the day-to-day changes during the adult phase.
5Insect Jelly Is the Main Food
Adults are mainly fed insect jelly, and commercial jelly products make feeding straightforward. Keep in mind that, given its large size, this species tends to get through more jelly than smaller beetles.
6A Sturdy Build and Prominent Horn
Males carry a large, well-developed horn and a powerfully built body. Because their strength matches their size, it's best to handle them calmly rather than trying to restrain them forcefully.
7Prepare the Setup in Advance
It's reassuring to have an enclosure, substrate, and temperature-control equipment suited to a large beetle ready before it arrives. During the larval stage in particular, you may need to move up to a bigger case as it grows.
