Dorcus japonicus
Coleoptera / Family: Lucanidae
- Total length
- 15-20 mm
- Range
- Tokunoshima*Although reported from Cape Sata, in mainland Kyushu, substantial populations have only been confirmed on Tokunoshima.
Although attracted to light, it primarily roams the ground. In the diorama, it seems to be wandering over a decaying log.
The body is black and covered with fine hairs. Both males and females have small mandibles. Its body appears brown due to the accumulation of mud and wood particles.
Although it is primarily found in secondary forests, it is less active than other stag beetles and is relatively scarce in number. Larvae metamorphose into adults in about one year.

Habitat of This Animal:
B:Forest along the mountain ridge - B1:Forest near the settlement
Most of the forests in Tokunoshima Island are secondary forests that were once cleared in the past. Especially near the settlements, there are forests that have become well-lit thanks to recent pruning. Remains of paths, charcoal kilns, and fields form a reminder of the relationship between people and nature. Such forests accessible from settlements are inhabited by many living creatures fond of the well-lit environment.
