Coptodera aerata
It is very instructive for me to see the dorsal habitus of Coptodera aerata which I believe is the very first image of this species posted on the internet! It has not been recorded in my state of WI. I notice a lot of glare in this picture. To reduce the shine, would photographing under diffused light be an option for you?

I should have used a different light for this one. I have changed the image and added a lateral view of the head.

Unfortunately, both of my specimens have greased out (making this look really ugly). I will try to degrease this specimen soon and reshoot for a better image.

With your diffused or redirected lighting I now better see the characteristic metallic green luster, although this species can also venture into blue reflections. How do you degrease beetles? Looking for cheap ways, I have had unsatisfactory results with hardware acetone, but much better luck with undiluted household ammonia -- available up to "industrial" concentration 10%.

New image, again
This one now looks better, and there are some bluish reflections present. I am using hexane right now to degrease, but I don't know how easy that is to get.

degreased image
Yes, a much improved image and apparently a valuable one for study as I've never seen a photograph of Coptodera published on paper or on the internet. Thank you!
