I found this rather interesting. I was not sure where to put it so mods feel free to move if need be

This is really an amazing little bug.

These insect "diamonds" are not made of carbon like the diamonds in a jewelry store, but instead contain the same sugar-based molecules called
chitin that comprise the rest of their outer cuticle. But the 3-dimensional arrangement of the sugar molecules is precise and orderly. In their report
published in the Journal of the Royal Society Interface, the researchers called them "biological photonic crystals that act as wavelength-specific
reflectors."1
The crystal-construction techniques employed by both butterflies and weevils so far exceed the current technological capacities of mankind that
engineers are going to try using these insects' organizational tactics as a template to produce new photonic materials.
In both cases, the study authors credited nature or evolution with the origin of these fine structures. But if insect technology is beyond the
capability of intelligent people, then shouldn't it rather be attributed to a source with even greater intelligence than man? Nature has no
intelligence and no intelligence proxy, leaving a divine Creator as the only possible cause.4 And He rightly deserves the credit for these brilliant
biological structures.

I have said it before and I will say it again, "What we know thus far is only a drop in the ocean to all there is yet to learn"
So any ideas on what types of photonic materials they hope to create using the this little jewel?
