Four-spotted rhinoceros beetle

Four-spotted rhinoceros beetle key facts

Care level

Advanced

Lifespan

Little data

Size

Little data

Diet

Adults take beetle jelly; larvae eat fermented substrate

Temperature & Humidity

There is little numeric temperature data. Many records come from the eastern Andean slopes, so keep it away from places where summer heat builds up.

Breeding & Egg-laying

Little is published on breeding. Provide deep fermented substrate for laying and rear larvae in the same.

Cohabitation

Keep adults singly and together only for mating.

Lifespan & Rearing Period

Larval duration and adult lifespan are poorly documented.

Health & Notes

Importing foreign stag and rhinoceros beetles is regulated by the Plant Protection Act and the Invasive Alien Species Act (species-name certificate), with each species needing clearance from the Plant Protection Station, so domestically bred stock is the safe choice. Never release captive beetles.

About Four-spotted rhinoceros beetle

The four-spotted rhinoceros beetle is a rare, small beetle from the eastern Andes of Peru, Ecuador, and Colombia, recommended for experienced keepers only.

7 things to know before welcoming a Four-spotted rhinoceros beetle

1. 1Best Suited to Experienced Keepers

   This species is recommended for experienced keepers because so much about its biology remains undocumented. If you're new to beetle keeping, it's best to build experience with more common rhinoceros beetles first.

2. 2A Poorly Documented Species

   Little is known about the Four-spotted rhinoceros beetle's lifespan or adult size, since both specimens and research on it are scarce. Expect to fill in the gaps yourself through careful day-to-day observation of your beetle's condition.

3. 3Native to the Andes

   This beetle has been recorded on the eastern slopes of the Andes in Peru, Ecuador, and Colombia. Since detailed habitat data is limited, temperature and humidity should be adjusted carefully, drawing on general rhinoceros beetle husbandry experience.

4. 4Rarely Available

   Both specimens and information on this species are scarce, so simply finding one to keep can be a challenge in itself. Checking regularly for availability is worthwhile if you're hoping to bring one home.

5. 5Larval Care Matters Most

   As with most rhinoceros beetles, how the larvae are raised strongly affects the adult beetle's condition. Keep a close eye on substrate changes and shifts in temperature or humidity throughout this stage.

6. 6An Adult Built for Observation

   The beetle's namesake spots and compact, well-proportioned build are its main appeal. This is a species better enjoyed through quiet observation than frequent handling.

7. 7Keep Gathering Information

   Because so little is documented about this species, connecting with other keepers and drawing on general beetle-keeping knowledge is invaluable. Make a habit of seeking out current information both before and after bringing one home.

Frequently asked questions about Four-spotted rhinoceros beetle

Q.How difficult is it to keep a Four-spotted rhinoceros beetle?

A.This species is considered suitable only for experienced keepers. Because so little documentation exists on its care and biology, you'll need to draw on experience with other rhinoceros beetles and adjust conditions through trial and observation.

Q.How long do they live, and how big do adults get?

A.Reliable data on both lifespan and adult size is currently very limited, so neither is well established. You'll need to observe your own beetle's condition as you go, since general figures aren't yet available.

Q.Where does this species come from?

A.It has been recorded on the eastern slopes of the Andes Mountains in Peru, Ecuador, and Colombia. Its species name refers to the four spots on its body and was first described by Waterhouse in 1881.

Q.Is the Four-spotted rhinoceros beetle covered by CITES?

A.No, the Four-spotted rhinoceros beetle falls outside CITES. Many live foreign Scarabaeoidea (stag beetles, rhinoceros beetles, flower chafers and relatives) are quarantine pests whose import is banned under Japan's Plant Protection Act, and even importable species require a species-name certificate from a foreign government body under the Invasive Alien Species Act (entry only via designated airports, never by international post). Whether a species may enter must be checked with the Plant Protection Station in advance, so choose domestically bred stock and never release captive beetles.

Q.Can beginners keep this species?

A.Since so little is documented about this beetle and it's considered a species for experienced keepers, it isn't recommended as a first species for someone new to insect keeping. It's better to first learn the basics with a more common, well-documented rhinoceros beetle before attempting this one.
