It was sunny and cold as nineteen volunteers contributed to this week's survey. The bright blue of the damselfly shown below is the result of light reflected by pteridine-containing nanospheres acting as pigments in its epidermis. The color is independent of viewing angle, which is not the case for the blue of the swallowtail butterfly shown next, on which microscopic structures of the wing scales produce the iridescent colors.
