Izu Miyama Stag Beetle

Izu Miyama Stag Beetle

The Izu Miyama stag beetle is a subspecies of Miyama stag beetle found only on Japan's Izu Islands. Its mandibles are short and thick, fully developed into what's known as the "Fuji" form, giving the beetle a strikingly powerful look. The ear-like projections on its head are less pronounced than in the mainland subspecies, and its body has a distinctive shape, with a relatively small upper body balanced by a sturdier lower half. The femurs often show well-developed yellowish-brown markings, adding another detail worth observing. Because keeping this beetle well requires attention to temperature and humidity, it's generally considered a beetle for experienced keepers — but for anyone drawn to island-endemic subspecies, it's a distinctive and rewarding one to raise.

关于Izu Miyama Stag Beetle

Discover the Izu Miyama stag beetle, a subspecies found only on Japan's Izu Islands, known for its thick Fuji-form mandibles and richly marked femurs. Best suited to experienced keepers due to its care needs.

迎接Izu Miyama Stag Beetle前需要了解的7件事

  1. 1Endemic to the Izu Islands

    The Izu Miyama stag beetle is a subspecies found only on Japan's Izu Islands. It shows regional traits distinct from the mainland subspecies, making it interesting to compare against other Miyama stag beetle populations.

  2. 2Powerful Fuji-form mandibles

    Its mandibles are short and thick, fully developed into the so-called "Fuji" form. This shape appears regardless of overall body size, giving every individual a strong, distinctive look.

  3. 3Understated head projections

    The ear-like projections on either side of the head are less pronounced than in the mainland subspecies. This subtler feature is one of the clues used to identify the Izu form.

  4. 4A distinctive body balance

    This beetle has a somewhat unusual build, with a relatively small upper body and a larger lower body. Comparing the overall silhouette makes the difference from other Miyama stag beetles easier to spot.

  5. 5Size varies between individuals

    Adults typically range from about 33.8 to 70.0mm in males and 25.0 to 43.9mm in females, with a recorded captive maximum of 68.7mm. Size varies noticeably between individuals, which makes each one worth observing closely.

  6. 6An active period of a few months

    Once active as an adult, this beetle typically lives for around two to three months, which is relatively short compared to some other insects. After bringing one home, it's worth checking in on it regularly during this limited period.

  7. 7Care suited to experienced keepers

    This species is generally considered suited to experienced keepers, since maintaining the right temperature and humidity takes some knowledge and care. If it's your first time keeping one, it's a good idea to research proper husbandry and prepare a case and substrate in advance.
