💡

Did You Know?

Like all horntails, the short horn-like projection at the tail is not a stinger but a structural feature called a cornus, present in both sexes.

Bordered Mantis

A large green mantis with two prominent dark eyespots on the inner surfaces of its forelegs. It uses these spots in its threat display by spreading its legs wide. It is common in South American forests.
