A 47-million-year-old fossil moth from Messel, Germany. The moth is in glycerine, which make its structural colors appear yellow.
A 47-million-year-old fossil moth wing looks yellow in glycerine. When the moth was alive, the colors would have appeared yellow-green.
An illustration of what the moth's wing patterns looked like in life.

Different scale types have different structures. This is an SEM image of a "satin-type" scale.

Complex structures in moth scales create the colors of the insects' wings. This is a transmission electron micrograph (TEM image) of a fossil scale showing curved surfaces in between the ridges.
