Spectabilis shining stag beetle

Spectabilis shining stag beetle key facts

Care level

Advanced

Lifespan

Adults a few months (genus accounts); 1-2 years from hatching to pupation

Size

Captive records 81.4mm (male) and 48.2mm (female); wild record 83.0mm (male)

Diet

Adults take sap or beetle jelly; larvae eat well-decayed wood and nitrogen-rich substrate

Temperature & Humidity

Odontolabis adults and larvae are cold-sensitive and cannot survive winter temperatures in mainland Japan, so always heat them in winter.

Breeding & Egg-laying

It is considered difficult. Odontolabis larvae favour humus and are reared on used substrate mixed with spent fungus-bottle contents or nitrogen-rich substrate, with red-rotted flake for harder species; the related O. lacordairei sometimes lays in red-rotted flake.

Cohabitation

Odontolabis are aggressive and males may kill an incompatible female. Never keep several together; house singly and supervise pairings.

Lifespan & Rearing Period

Odontolabis adults live a few months, and about six weeks after becoming active their tarsi and antennae start to die back rapidly. Development from hatching to pupation takes one to two years, so pair adults soon after they become active.

Health & Notes

It closely resembles O. lacordairei and O. yasuokai, so check the underside markings, locality and scientific name. Importing foreign stag and rhinoceros beetles is regulated by the Plant Protection Act and the Invasive Alien Species Act (species-name certificate), with each species needing clearance from the Plant Protection Station, so domestically bred stock is the safe choice. Never release captive beetles.

About Spectabilis shining stag beetle

A stag beetle native to Sumatra, known for its glossy body and yellow-tinged elytra. Considered a species for experienced keepers, with a larval stage of one to two years and an adult lifespan of just a few months.

7 things to know before welcoming a Spectabilis shining stag beetle

1. 1Best suited to experienced keepers

   The Spectabilis shining stag beetle is considered one of the more difficult stag beetles to keep. It requires careful management of temperature and humidity, so it's best approached after gaining some experience with stag beetle keeping.

2. 2Distinguishing it from Lacordaire's

   It closely resembles the yellow-winged Lacordaire's stag beetle, but can be distinguished by its less prominent yellow markings on the underside. It's worth checking this feature when choosing an individual.

3. 3A one- to two-year larval stage

   From hatching to pupation, this species follows a slow growth cycle spanning roughly one to two years. Patience is needed while watching it develop into an adult.

4. 4Adults live only a few months

   Adult beetles remain active for only a few months. Keepers can make the most of this limited window by enjoying the day-to-day changes closely.

5. 5Typical size range

   Captive-bred records stand at 81.4mm for males and 48.2mm for females, with a wild record of 83.0mm for males. Size varies considerably between individuals, adding to the enjoyment of watching each one grow.

6. 6Temperature and humidity matter

   Being native to Sumatra, this species tends to prefer warm, humid conditions. It's important to choose a suitable location and management routine to keep temperature and humidity stable inside the enclosure.

7. 7Preparing before you bring one home

   Since this is considered a species for experienced keepers, it's best to have the necessary equipment and environment fully set up beforehand. Regular observation will help you notice changes in condition or activity early on.

Frequently asked questions about Spectabilis shining stag beetle

Q.Is the Spectabilis shining stag beetle listed under CITES?

A.No, the Spectabilis shining stag beetle is not subject to CITES. Many live foreign Scarabaeoidea (stag beetles, rhinoceros beetles, flower chafers and relatives) are quarantine pests whose import is banned under Japan's Plant Protection Act, and even importable species require a species-name certificate from a foreign government body under the Invasive Alien Species Act (entry only via designated airports, never by international post). Whether a species may enter must be checked with the Plant Protection Station in advance, so choose domestically bred stock and never release captive beetles.

Q.Is this species suitable for beginners?

A.The Spectabilis shining stag beetle is considered one of the more difficult stag beetles to keep, and is best suited to experienced keepers. It's recommended to gain some stag beetle keeping experience before taking one on.

Q.How long does this species live?

A.Adults are active for only a few months. The larval stage, however, takes roughly one to two years from hatching to pupation.

Q.How large does it grow?

A.Captive-bred records stand at 81.4mm for males and 48.2mm for females, with a wild record of 83.0mm for males. Size varies considerably between individuals and rearing conditions.

Q.How can it be told apart from Lacordaire's stag beetle?

A.Both species have yellow elytra and look very similar, but the Spectabilis shining stag beetle can be distinguished by its less prominent yellow markings on the underside.
