Watching the extremely rare and heterosexual 5-horn rhino

The five horned beetle (Eupatorus gracilicornis) will make many people 'stunned' because of its very large size and a unique shape.

An adult male beetle is nearly 8cm long, its body is shiny black, its wings are brown outside.

Most impressive are 5 sharp pointed horns, a long and curved one on the top of the head, the remaining 4 shorter, located on the front chest plate.

These horns are the fighting weapons of males. It is used to 'wrestle' opponents, not to damage, because this insect has a steel-like outer shell.

Although it looks very heavy, the five-horned beetles can fly quite flexibly.

Female females have the same color as males, but their heads and chest do not have horns.

This hard-winged insect lives only in cold climates.

In Vietnam, they are caught in Lao Cai, Cao Bang, Ha Giang, Hoa Binh and Lam Dong.

Due to its large size and unique shape, the five-horned beetles were hunted for sale to international insect collectors.

It is estimated that their number of individuals in Vietnam is only a few thousand.

In the Vietnam Red Book, the five horned beetles are among the few species of insects that are listed as endangered.

Without effective defense measures, the 'five horn rhino' is at risk of sharing the tragic fate of one-horn rhino in Vietnam, which is extinct. (Photo: Internet)
