Rare Scarab Beetle in Costa Rica Looks Like It’s Made from Chrome

A truly amazing little Scarab beetle found in Central America.

A rare Chrysina limbata scarab beetle photographed in Costa Rica, its shell displaying a near-perfect metallic mirror surface — a biological phenomenon produced by nanoscale light interference rather than any pigment, making this insect a natural photonics experiment that evolution arrived at long before materials science

Beetles come in manner of form and color, with over 30,000 types of Scarab beetles alone.

Many of them are known for their colorful shells, adorned with all manner of pattern and hue.

Michael Farmer in Costa Rica recently came across a rare beetle on his property, one that looks like it as made of polished chrome. At first glance, it seems impossible that this could be a living creature, and even Farmer is clearly visible in its reflection.

Known as Chrysina limbata, this beautifully shiny specimen is quite the sight to behold, reflecting Farmer and his camera perfectly in the photographs.

What Makes this Beetle So Reflective?

Unlike any metal plating, Chrysina limbita’s gleaming silver appearance comes from its exoskeleton’s microscopic structure. Layers of chitin create a natural thin-film interference that reflects up to 97% of visible light.

Flip through the photos below to see what a magical little creature this beetle is. Nature always has more ways to impress us. Via MyModernMet:

Why We Love It

This beetle is one of those rare moments where nature seems to borrow design straight from modern art. Its shimmering shell, sculpted by evolution, reminds us that even the tiniest creatures can leave us breathless.
