Antaeus Stag Beetle
The Antaeus stag beetle is a large species native to the Himalayan mountain range. Its short, thick mandibles and glossy, powerfully built body make it a favorite among beetle keepers. While generally calm in temperament, its mandibles are strong, so handling should be done with care to avoid getting pinched. Being nocturnal, it tends to stay still in hiding spots during the day and prefers a quiet, undisturbed environment. Adults live for one to three years, making this a beetle you can enjoy caring for over the long term — a good choice for keepers who already have some basic experience with beetle care.

7 things to know before welcoming a Antaeus Stag Beetle
1Sensitive to Heat (Himalayan Origin)
The Antaeus stag beetle originates from the cool climate of the Himalayas. Keep it out of direct sunlight and high summer heat, in a cool, well-ventilated spot.
2Handle the Powerful Jaws with Care
Its short, thick mandibles are stronger than they look and can pinch painfully. When picking it up, hold the thorax firmly and keep your fingers away from the jaws.
3Never House Two Males Together
Males are highly territorial, and housing two together can lead to serious fighting and injury. Keep each beetle in its own separate enclosure.
4Insect Jelly Is the Main Food
Adults are fed primarily on commercial insect jelly. Check regularly that the jelly hasn't dried out or run low, and keep it topped up.
5Humidity Management Matters
If the substrate dries out too much, the beetle's condition can suffer. Lightly mist it when the surface looks dry, but avoid making it overly wet.
6Nocturnal — Quiet Days, Active Nights
It tends to stay still in hiding during the day and becomes active at night. Place the enclosure somewhere calm, away from direct sunlight and vibration.
7A 1-3 Year Companion
Adults typically live for one to three years. With consistent care of temperature, humidity, and food, you can enjoy its presence for a long time.
