Dorcus schenklingi
A large giant stag beetle endemic to Taiwan, shaped like an oversized Dorcus rectus. Males reach 92mm, the largest stag beetle in Taiwan. Fierce-tempered and protected in the wild; only captive-bred stock circulates in Japan.
Schenkling's giant stag beetle (Dorcus schenklingi) is a large Dorcus endemic to Taiwan, living in primary forest at 800-2,500 m, chiefly in mid-elevation mountains at 1,300-1,800 m. Shaped like an oversized D. rectus, males measure 35-92mm and females 40-50mm; large males exceed 90mm, making it the largest stag beetle in Taiwan and one of the largest in the genus. Adults emerge from May to August, are nocturnal, come readily to lights and gather at sap of Fagaceae; larvae develop in decaying broadleaf wood. Habitat fragmentation, collecting pressure and deaths at road lights have reduced numbers, and it is listed as a Category II protected species (rare and valuable) under Taiwan's Wildlife Conservation Act, with collection and sale prohibited without permits. Only captive-bred descendants of earlier imports circulate in Japan. It is fiercer than other Dorcus and dominates the Taiwanese D. hopei formosanus when housed together. Males may attack females even after mating, so pair under supervision. Rearing follows D. hopei; room temperature works, but keep summers below 30C. The BE-KUWA 2025 captive record is 89.9mm (2013) and the wild maximum 84.0mm.

Beetle jelly; larvae on fungus bottles or fermented substrate
Room temperature works. Keep summers below 30C; activity slows under 18C. A highland species, so beware of heat.
Eggs are laid in decaying logs or fermented substrate; rear larvae on fungus bottles. Males may attack females even after mating, so pair briefly under supervision.
Fierce-tempered; house both sexes singly and never with other species.
No species-specific source for lifespan or larval period. As is usual in Dorcus, adults live several years.
Category II protected in Taiwan; collection and sale are banned. Japanese stock is captive-bred only, so verify the line's origin.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Schenkling's Giant Stag Beetle is 18℃. Avoid sudden temperature changes and maintain a stable environment.
