Amami Saw Stag Beetle
The Amami Saw Stag Beetle is found only on Amami Ōshima and Kakeroma Island, making it the largest species in Japan's saw stag beetle genus. Its deep black body and thick, sweeping mandibles are its defining features, with recorded lengths reaching 82.1mm in captivity and 80.5mm in the wild. These beetles tend to be feisty, and males housed together often fight, so keeping them individually is standard practice. Their bold mandibles and striking presence make them a favorite among stag beetle enthusiasts. Because care calls for some experience, keepers should have the basics — temperature control, substrate choice — in place before bringing one home.

7 things to know before welcoming a Amami Saw Stag Beetle
1Endemic to the Amami Islands
This species is found only on Amami Ōshima and Kakeroma Island, nowhere else in the world. That narrow range makes it a prized and distinctive beetle among Japanese stag beetle keepers.
2Japan's largest saw stag beetle
This is the largest species in Japan's saw stag beetle genus. Males range from 23.4mm up to 82.1mm in captivity, with a wild record of 80.5mm, and their thick, curved mandibles are the main visual draw.
3Best suited to experienced keepers
Care is rated for intermediate-level keepers, so understanding basics like temperature, humidity, and substrate selection helps a lot. First-time keepers may want to build up some experience before taking one on.
4A somewhat feisty temperament
Males will use their mandibles to fight one another, so housing multiple males together isn't recommended. Keeping them individually helps prevent injury and unnecessary stress.
5Adult lifespan is relatively short
In the wild, adults live for roughly 2 to 3 months. Because that window is short, providing a good environment from the moment you bring one home matters.
6A striking, all-black body
The body is uniformly black with a glossy finish that contrasts sharply with the thick mandibles. It's a species that really shows off the bold, dramatic look typical of saw stag beetles.
7Prepare the setup beforehand
Before bringing one home, prepare a ventilated enclosure, insect substrate, and climbing branches. Since this species comes from the warm Amami region, choose a spot that avoids extreme cold.
