What is cyclommatus elaphus?

Cyclommatus elaphus is a species of stag beetle that is native to Southeast Asia, specifically found in countries such as Indonesia, Malaysia, and the Philippines. It is known for its large size and impressive weaponry - the males of the species have long, curved mandibles that can be used for fighting and mating displays.

These beetles prefer forested areas and are particularly abundant in rainforests. They feed on sap and fruit, and the larvae live in rotting wood. Due to habitat loss and deforestation in its native range, the Cyclommatus elaphus population is thought to be declining and is considered a vulnerable species.

The unique appearance of these beetles, particularly their large mandibles, has made them popular among collectors. However, trade in these beetles is often illegal and can contribute to further declines in populations. Conservation efforts are underway to protect these fascinating insects and preserve their habitat.
