Chlaenius sp. ground beetle, Urbana, Illinois
This colorful beetle came from our back yard.Â It's a ground beetle in the genus Chlaenius, recognizeable from its pubescent elytra and pungent defensive secretions.Â Like most ground beetles, Chlaenius makes a living as a predator.
The beetle's metallic sheen is not the result of a pigment but of fine microscopic sculpturing on the integument.Â This is evident when the insect is viewed at a different aspect: notice how the color turns to green in lateral view:
The same beetle, in sideview.

Beautiful photo with no glare from the flash. Subtly striking.
Oho! A multilayer reflector, very nice. Now you've got to get your hands on one of those loxandrines with diffraction gratings. :)
Wow! Great shots. That second profile view is stunning... Fascinating detail on the color change, too.
