Second stack, need more I.D. help please!

Post by Tom Stack »

Shot this beetle every-which-way to no avail. Simply too difficult to make eye contact here. Can anyone help with I.D.?

This shot about 2X - 3X life size with Canon MP-E 65, 1/250 f11, stack of 6 images in Helicon.

Thanks,

Tom

Hard to tell from just the face. With those big mandibles and bluish black color, my first impression is ground beetle, order Coleoptera, family Carabidae. http://bugguide.net/node/view/186/bgimage

Can you post an overall body shot, straight down from above?

BTW, with these shiny dark beetles, it takes very broad diffused lighting to show off their features. With a small light source, most of the mirrored surfaces just reflect dark surroundings and go black as a result. Try surrounding your subject with a foam cup or some packaging foam.

Edit: to add lighting suggestion.

Beetles are incredibly diverse, would need to see a lot more of this beast to even attempt an ID.
However, the large jaws are suggestive of a Ground Beetle (Family: Carabidae).

The subfamily and genus are quite easy: Scaritinae, genus Pasimachus.

I will even lean a bit further out of the window and say this is Pasimachus strenuus (the species that occurs in Florida).

Cheers

Once again absolutely amazing response time! Thank you Harry!

Just to be sure, I'll take a full body shot from above and post it.

Rik, I hear you about the lighting! I did have packaging material as a diffuser on the strobes and tyvek over the critter to the point where
f11 at 1/250 was starting to be a bit dark with the MT-24 twin light.
Yes, I agree, more diffuse lighting would have worked better!

Best,

Tom
