Emerald Eupholus Weevil

A spectacular weevil with brilliant turquoise and black bands across its elytra. It is found only in the rainforests of New Guinea.

💡

Did You Know?

Its stunning blue-green color comes from photonic crystals in tiny scales covering the exoskeleton similar to how opals produce color.

Crawling Water Beetle

A tiny, oval water beetle with a yellowish body covered in rows of dark punctures. Unlike diving beetles, it crawls slowly among aquatic vegetation rather than swimming actively.

💡

Did You Know?

It stores air beneath enlarged hind coxal plates, which act as a built-in oxygen reservoir while submerged.
