Moved from Vivid Metallic Ground Beetles.

This looks like a species of Chlaenius, or at least something in that tribe. Careful, they have an incredibly penetrating odor:-)

The head and pronotum look more coppery and the elytra a little bluer in ambient light.

Collected, along with several other carabid species and two land planaria, under a stones and small logs in my yard. This one and the smaller one under it are drinking from a large drop of water I placed on the milimeter rule. It's one of my photography secrets that I'll share:

I put about 10 beetles into my "light arena," a 360-degree lighting contraption I built for shooting small subjects. They run frantically around, looking for a way out and are consequently difficult to photograph. But I've learned that after racing around, carabids build up a thirst and will pause to drink if you place some water in their midst. You can focus and shoot just fine while they're drinking.

For flower-visiting cerambycids, I put out a little honey water or molasses water. They quit running and flying and have a little refreshment.

My final tip: The inside of my light arena is painted with Insect-a-slip, available from BioQuip.com. It's so slippery it keeps even ladybugs from climbing the walls.
