Moellenkamp's Beetle

Moellenkamp's Beetle key facts

Care level

Intermediate

Lifespan

Adults 6-12 months, larvae 14-18 months

Size

Males 60-115mm (rarely over 130mm), females 45-60mm

Temperature

20〜25℃

Diet

Beetle jelly (adults), fermented flake soil (larvae)

Temperature & Humidity

As a highland species keep at 20-25C, slightly cooler than the Caucasus beetle, with air conditioning in summer. Avoid waterlogged substrate.

Breeding & Egg-laying

Use deep, firmly packed well-fermented or black-soil substrate; laying continues for 1.5-2 months. Both sexes tend to burrow.

Cohabitation

Highly combative; males may attack and kill females. Pair briefly under observation and otherwise house singly.

Lifespan & Rearing Period

Adults live 6-12 months; larvae take 14-18 months (males) or 14-16 months (females), so sexes often emerge out of step.

Health & Notes

Larvae often yield short-horned adults despite large bodies; producing long-horned giants is the main challenge. Imports need a species-name certificate.

About Moellenkamp's Beetle

Moellenkamp's Beetle is a Borneo-endemic, three-horned species known for its tall, narrow body and nearly parallel thoracic horn. It's sensitive to heat, so keeping temperatures on the cooler side is key.

7 things to know before welcoming a Moellenkamp's Beetle

1. 1Keep It Cool

   Moellenkamp's Beetles come from high-altitude regions and don't tolerate heat or humidity well. Use air conditioning or another method to keep the enclosure on the cooler side.

2. 2A Distinctive Build

   Compared to relatives like the Atlas and Caucasus beetles, this species has a narrower, taller body. Males' thoracic horns run nearly parallel, giving them a striking, different presence.

3. 3Size Varies

   Males typically reach 60–115mm, with rare individuals exceeding 130mm. Females are smaller, around 45–60mm, and don't have horns.

4. 4Long Larval Stage

   The larval stage lasts a lengthy 14–18 months before reaching adulthood. Regular substrate changes and steady temperature control require patience over that time.

5. 5Adult Lifespan

   Once they reach adulthood, these beetles typically live 6 months to a year. Since their adult time is limited, it's worth observing and caring for them closely day to day.

6. 6Intermediate Level

   This species is considered suitable for intermediate keepers. Some prior experience with beetle care, particularly around temperature management, will help.

7. 7Prepare Your Setup First

   Because heat sensitivity is a key concern, confirm you can keep the enclosure cool before bringing one home. This matters especially in summer, so check the room temperature in advance.

Frequently asked questions about Moellenkamp's Beetle

Q.How big does Moellenkamp's Beetle get?

A.Males typically reach 60–115mm, with rare individuals exceeding 130mm. Females are smaller, around 45–60mm, and don't have horns.

Q.How long do they live?

A.The larval stage lasts a long 14–18 months, and adults typically live another 6 months to a year. Including the larval period, you're looking at nearly two years with this species.

Q.Is this beetle suitable for beginners?

A.It's generally considered suitable for intermediate keepers. Some prior beetle-keeping experience helps, especially with temperature management.

Q.What should I know about temperature control?

A.This species comes from high-altitude habitats and doesn't tolerate heat well, so it needs to be kept slightly cooler than typical beetles. Be especially careful not to let room temperature rise too high in summer.

Q.Is this species subject to any special regulations?

A.Moellenkamp's Beetle is not subject to CITES.
