Can beginners keep Brooke's Stag Beetle?

Brooke's Stag Beetle is generally considered a species for experienced keepers, since it requires careful temperature and humidity control as well as confident handling around its mandibles. It's best suited to those with prior insect-keeping experience or who are willing to research care thoroughly beforehand.

Can its mandibles pinch me?

Yes — the large, curved mandibles have a strong grip, and careless handling can result in a pinch. When picking the beetle up, hold it by the thorax or another spot away from the mandibles.

What should I feed it?

Standard commercial insect jelly works fine as the main food, with no special preparation needed. Just check periodically that the jelly hasn't dried out or spoiled.

How long do adults live?

Adults typically live around six months to a year, which is on the shorter side compared with many other stag beetles. Because of this, it's worth cherishing the time you spend observing them from the day you bring them home.

Is it okay to keep multiple beetles together?

Keeping multiple males together isn't recommended, since they can fight fiercely with their mandibles. If you want to keep more than one, house them in separate enclosures.

Brooke's Stag Beetle

Brooke's Stag Beetle is a large stag beetle species native to Borneo, prized for its dramatically curved mandibles and glossy black body that gleams almost like polished lacquer. Adults grow to an impressive 50–90mm, giving them a striking, almost sculptural presence that appeals to serious collectors. Like most stag beetles, they are nocturnal, spending daylight hours tucked away and staying calm and easy to handle. That said, keeping them healthy calls for careful attention to temperature and humidity, which is why this species is generally recommended for experienced keepers. Adults typically live six months to a year, making every day spent observing them feel worth savoring.

Brooke's Stag Beetle from Borneo features curved mandibles and a glossy black body, reaching 50–90mm as an adult. Adults live 6 months to a year; best suited to experienced keepers.

7 things to know before welcoming a Brooke's Stag Beetle

1Temperature & Humidity
Brooke's Stag Beetles thrive in warm, humid conditions but are also vulnerable to poor ventilation, so keeping the substrate moist without letting it turn stagnant matters. Avoid sudden temperature swings and keep the enclosure out of direct sunlight.
2Handle the Mandibles with Care
The large, curved mandibles deliver a strong pinch, so careless handling with bare hands can result in a nip. When picking it up, hold the thorax or another spot away from the mandibles.
3Mostly Still During the Day
Being nocturnal, they spend most of the day resting quietly, whether burrowed in the substrate or tucked against a climbing branch. Little daytime movement is completely normal, so don't judge their health from that alone.
4A Relatively Short Adult Life
Adults typically live six months to a year, which is relatively short compared with many other beetles. Keep this in mind from the start, and enjoy observing the changes each day brings.
5Feeding is Simple
Their main food is commercially available insect jelly, so no special preparation is needed. Check regularly that the jelly hasn't dried out or gone stale, and keep it fresh.
6Best Kept Separately
Males can fight fiercely with their mandibles, so if keeping more than one, it's best to house them separately. Keeping them together risks injury from pinching.
7Suited to Experienced Keepers
Because it calls for careful temperature and humidity management along with confident handling, this species is considered suited to experienced keepers. It's best for those with prior insect-keeping experience or who are ready to research thoroughly beforehand.
