Answer: Dragonfly wing (macro)
by IgneousRex · 18 guesses · hard

What you're looking at
This is a dragonfly wing, one of nature's most sophisticated flying instruments. Dragonflies have been around for over 300 million years and are found near almost any body of water, from ponds and lakes to streams and marshes. Their wings are a marvel of engineering that allows them to perform acrobatic manoeuvres no other insect can match.
When magnified this close, a dragonfly wing reveals an intricate lattice of veins running through a nearly transparent membrane. The pattern looks more like stained glass or a circuit board than anything you'd expect from an insect. Without the familiar silhouette and body of the dragonfly visible, this delicate network of lines and geometric cells becomes almost unrecognisable to the human eye.
Search for fine networks of intersecting lines creating regular polygonal patterns in macro insect photography.
