Can beginners keep this species?

How much do males and females differ in size?

Males range from 35 to 92 mm, while females range from 40 to 50 mm. Males show especially wide variation in size, and the largest individuals rank among Taiwan's biggest stag beetles.

Is it aggressive, and can multiple beetles be kept together?

Yes, this species has a somewhat aggressive temperament, and housing multiple individuals together in one case can lead to fighting. Both males and females are best kept one per enclosure.

How long does it live?

7 things to know before welcoming a Schenkling's Giant Stag Beetle

1Keep Them Solo
Schenkling's Giant Stag Beetles have an aggressive temperament, and housing multiple individuals in the same case can lead to serious fighting. This applies not only between males but also between males and females. As a rule, house each beetle in its own separate container.
2Mimic Its Native Climate
Native to Taiwan, this species tends to prefer warmer conditions than Japan's average climate. Take particular care in winter to prevent the enclosure from getting too cold, and avoid sudden temperature swings.
3Powerful Size and Jaws
Males can reach up to 92 mm, making this Taiwan's largest stag beetle species, and its powerful mandibles are a major highlight. Handle it carefully during maintenance, as a bite from those jaws can deliver a strong pinch.
4Captive-Bred Lineage
Because this species is protected in its native Taiwan, the individuals available in Japan are captive-bred descendants raised through generations. Knowing this background can deepen your appreciation as you care for one.
5Best for Experienced Keepers
This species is generally considered suitable for intermediate-level keepers. Because managing temperature, humidity, and the particular needs of a large-bodied species takes some know-how, it's best to have some basic stag beetle keeping experience first.
6Size Difference Between Sexes
Males range from 35 to 92 mm while females range from 40 to 50 mm, showing much greater size variation among males. Keep in mind that individuals of the same species can differ quite a bit in size.
7Prepare a Suitable Enclosure
Since this is a large-bodied species, it's reassuring to prepare a reasonably spacious case and appropriate insect substrate in advance. Set up your enclosure and environment before bringing one home.
