The Canaliculatus Long-jawed Stag Beetle hails from the Sumatra region and belongs to the diverse Cyclommatus group of long-jawed stag beetles. Its name comes from the channel-like grooves etched into its wing covers, and males are known for their strikingly long, slender mandibles that can dwarf the rest of the body. The species splits into five subspecies by locality, each with its own subtle differences in build and coloring. Keeping one calls for some prior experience, making it a rewarding pick for intermediate keepers who want to watch a truly dramatic jaw take shape.

7 things to know before welcoming a Canaliculatus Long-jawed Stag Beetle
1Five Subspecies, Five Looks
This beetle is split into five subspecies by locality, each with its own body shape and coloring. Check the locality listed before bringing one home if you have a particular look in mind.
2Handle the Jaws with Care
The male's long, slender mandibles are the beetle's main draw, but that same slenderness makes them fragile. Set up an enclosure where it won't thrash around, and always handle it gently.
3Adults Live About 4-6 Months
As with the genus generally, adult activity typically lasts around four to six months. Keeping temperature and humidity stable helps the beetle make the most of that limited window.
4Suited to Intermediate Keepers
This species calls for some working knowledge of temperature and humidity control. First-time keepers may want to build experience with an easier stag beetle before taking one on.
5Substrate and Footholds
Adults do well with a moisture-retentive insect substrate plus bark or a perch so they can right themselves if they tip over. Aim for an environment that never dries out completely.
6Watch Day-Night Swings
Native to the warm, humid Sumatra region, this species doesn't tolerate sudden cold snaps or dryness well. Keep the enclosure away from direct sun and air-conditioning drafts.
7Males Vary Widely in Size
Male adults range from 23.6mm to 58.3mm, with real variation even within the same subspecies. Consider mandible shape and overall balance, not just size, when choosing one.
