Common blue damselfly

Seventh prize. This projection of a series of confocal microscope images shows the regular, crystal-like architecture of the eye of a common blue damselfly (Enallagma cyathigerum), an active visual predator and a swift flyer.

The area covered in the photo, which was taken by Dr. Igor Siwanowicz, measures about 0.6 x 0.8 mm; the image is a composite of two overlapping confocal image stacks.
