Can beginners keep this species?

Yes, it's considered an entry point into the Hexarthrius genus thanks to its hardiness and larvae that thrive on either fungus substrate or mat. Basic temperature and humidity management is usually enough to keep it trouble-free.

How long do adults live?

Adults typically live around four to seven months. Make sure to keep insect jelly or similar food available throughout that time.

How large do males and females grow?

Males grow to roughly 41-85mm and females to about 37-45mm. Mandible development in males varies considerably between individuals.

How does it differ from the Parry's stag beetle?

The two share a similar body shape, but Buquet's Stag Beetle is black all the way through its elytra. It lacks the reddish elytra seen on the Parry's stag beetle.

Are there any CITES restrictions?

Buquet's Stag Beetle is not listed under CITES. There are no international trade restrictions to worry about on that front.

Buquet's Stag Beetle

The Buquet's Stag Beetle is a striking all-black stag beetle native to Java. Its mandible tips curve into elegant, crab-claw-like forks, giving it a body shape similar to the Parry's stag beetle but without the reddish elytra, resulting in a glossy, uniformly black look. It's a hardy species whose larvae grow well on either fungus-based substrate or plain insect mat, making it a favorite entry point into the Hexarthrius genus. Adults live around four to seven months, and males with well-developed mandibles make an impressive centerpiece for anyone taking on their first stag beetle.

About Buquet's Stag Beetle

An all-black stag beetle from Java with crab-claw-shaped mandibles. Hardy and easy to raise on either fungus substrate or insect mat, it's a popular entry point into the Hexarthrius genus.

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

1Crab-Claw Mandibles
The mandible tips fork sharply like a crab's pincers, its most distinctive trait. The body is a glossy uniform black, unlike the similarly shaped Parry's stag beetle, which has reddish elytra.
2Wide Size Range in Males
Male body length varies widely within the species, from 41mm to 85mm. Larger individuals develop more pronounced mandibles for a more striking appearance.
3Larvae Thrive on Either Substrate
Larvae grow well on either fungus-based bottles or plain insect mat, making equipment easy to source and the species suitable for first-time larva keeping. Avoid sudden temperature swings and drying out of the substrate.
4Adult Lifespan Is Brief
Adults live for roughly four to seven months. Keep insect jelly or similar food on hand at all times and make the most of this limited window of care.
5Don't House Males Together
Males are territorial, and housing two together can lead to fighting and injury. When keeping multiple beetles, give each male its own case.
6Prepare Supplies Beforehand
Have the basics ready before your beetle arrives: a case, insect mat, climbing branches, and insect jelly. Set up the enclosure so the beetle can right itself if it flips over.
7A Great Beginner Species
Hardy and low-maintenance, it's widely regarded as an entry point into the Hexarthrius genus. It's a great choice for anyone trying stag beetle keeping for the first time.
