About
Allotopus moellenkampi moseri is a subspecies of the golden stag beetle Allotopus moellenkampi, found in highland areas of Borneo and nearby regions. Its hallmark is a brilliant golden coloration that appears gold under dry conditions and darkens when humidity is high. Males typically reach about 40–75 mm. In captivity a small to medium enclosure with footing to prevent toppling is used, and adults are fed insect jelly. Fine-particle fermented substrate is used for oviposition, and larvae are reared in fungal substrate bottles or high-quality substrate. Requiring careful temperature and humidity control, it is a beautiful species suited to more experienced keepers.
