Allotopus moellenkampi
A golden-colored Allotopus stag beetle species. A beautiful species from Borneo highlands.
Allotopus moellenkampi, the Moellenkamp's golden stag beetle, inhabits highland forests of Borneo and is one of the most accessible representatives of the coveted Allotopus genus. The entire body shimmers in a brilliant golden metallic sheen, with adults reaching 40–75 mm in length. Humidity management is paramount—the enclosure must remain consistently moist, as desiccation is rapidly fatal. Larval rearing requires reishi (Ganoderma) fungal wood or equivalent specialized substrate; standard fungal substrate bottles are generally unsuitable. Egg-laying also requires appropriate fungal wood. Adults live approximately 3–6 months. Compared to other Allotopus species, A. moellenkampi is relatively more available in the trade, making it the recommended entry point for collectors drawn to the spectacular golden stag beetles.
The Moellenkampi Stag Beetle lives Adult 3-6 months.
The Moellenkampi Stag Beetle grows to 40-75mm.
As a highland species, it cannot tolerate heat; captive temperatures must be strictly maintained at 18–24°C.

A highland species that dislikes heat, so cool management at 18-24°C is essential. Always keep the case highly humid and never let it dry out.
Humidity control matters most, so use a case that holds moisture well. Recreate the cool, damp conditions of the Bornean highlands.
Feed adults beetle jelly. Raise larvae on reishi wood or reishi mushroom substrate, as ordinary kinshi bottles are unsuitable.
Use dedicated mushroom substrate or reishi wood for egg laying. It will not lay in ordinary breeding logs, so prepare these in advance.
Adults live only about 3-6 months. Drying out is fatal, so check misting and substrate moisture every day.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The average lifespan of Moellenkampi Stag Beetle is Adult 3-6 months. With proper care and nutrition, they can live a long and healthy life.
Moellenkampi Stag Beetle typically reaches 40-75mm as an adult. Size may vary depending on care conditions and individual genetics.
