Megasoma elephas—often called the Elephant Beetle—is one of the largest and most impressive rhinoceros beetles in the world. Native to the tropical forests of Central and northern South America, it’s a species defined by power, bulk, and a surprisingly gentle temperament. Males are unmistakable: their long, forward‑curving cephalic horn and two stout thoracic horns give them a prehistoric look, while females are hornless but equally robust. Adults are covered in a dense layer of fine, velvety setae that give them a soft, dusty appearance ranging from tan to dark brown. This “fur” helps them blend into tree bark and absorb moisture in their humid forest environment.
 
In the wild, M. elephas inhabits lowland and mid‑elevation rainforests, where larvae develop deep within decaying hardwood logs. The larval stage is long—often 18–36 months—and produces enormous grubs capable of reaching well over 100 grams. Pupation occurs inside a thick, compacted chamber, and disturbance at this stage can be fatal, which is why keepers treat late L3 larvae with extreme care. Adults are surprisingly short‑lived by comparison, typically surviving 3–6 months, feeding on tree sap, fermenting fruit, and nectar.
 
In captivity, the species is considered advanced but highly rewarding. Larvae require nutrient‑rich, well‑rotted hardwood substrate, kept consistently moist and deep enough for natural cell construction. Adults thrive at 22–26°C with moderate humidity and excellent ventilation, and they benefit from sturdy climbing structures due to their size and weight. Their sheer mass, slow movements, and iconic horns make Megasoma elephas one of the most sought‑after rhinoceros beetles in the hobby—an impressive species that commands attention whether you’re a breeder or simply an admirer of giant insects..
