Salt marsh moth

I found this adorable fuzzy moth on the sidewalk, alive but lethargic from the damp drizzle, and lifted it up onto a railing where it wouldn't get stepped on.

Giant Swallowtail

When I found this butterfly, it was completely motionless. Closer inspection, however, showed that it was alive though torpid in the chilly morning. I let it crawl onto my finger, and my mammalian body heat must have given it a jump-start, because it fluttered out of sight.

Prehistoric iridescence


Although the original colors of the fossil moths were not preserved, the researchers were able to reconstruct them because the tiny color-producing patterns in the moth scales were intact. "The level of detail preserved in the scales of the fossil moths is just spectacular", said McNamara. The fossil moths owe their color to a stack of layers inside the scales. These layers form a fossil multilayer , which usually produces iridescent colour that changes depending on viewing angle. But other details of the fossil scales suppressed this effect, producing instead muted colors. "The moths basically wanted to appear the same colour from different angles – they didn't want flashy iridescence" said McNamara.
Full story at Physorg.

Also, iridescence in animals may go back as far as the Cambrian era:
At different times of day and different viewing angles, the marine creatures [Wiwaxia, Canadia, and Marella] would have glowed blue, red, yellow, or green. Since the evolution of these worms coincides with the first appearance in the fossil record of animals with eyes, such as trilobites, the twinkling colors may have warned predators to avoid these armored, and perhaps unpalatable, animals.
When I was a child, the color of prehistoric animals was presented as an unknowable mystery. But now, discoveries like these are commonplace-- but no less wonderful for it.

Monarch's wing

No butterflies were harmed in the making of this photo-- I found that detached wing on the sidewalk about two years ago, and preserved it in the plastic box seen here.

Prodryas

Prodryas
19th century engraving of Prodryas persephone, a fossil butterfly 
A version of this image appears in a book with the delightfully Victorian title Frail Children of the Air. Ironic, then, that this "child of the air" has become anything but frail in death, having been pressed and preserved in stone. On the original fossil, one can even see ghostly hints of veins, scales, and patterns on its wings.
