Ground beetle? - Chlaenius emarginatus

Ground beetle? - Chlaenius emarginatus
Bullitt County, Kentucky, USA
March 14, 2016
Size: 3/4 inch?
Very wet under a decaying log - found this guy and didn't appreciate all the shiny colors until cropped! Looked different colors depending on the angle of view. Think it is one of the ground beetles but not sure. One shot shows small larvae on its forelegs - possibly feeding on them.

Chlaenius emarginatus
The third photo shows the characteristic long mandibles with emarginate labrum, second photo shows pronotum with nonsinuate sides.

Moved from ID Request.

I linked your images...
Also, I believe the "larvae" on the third image are actually the expanded front tarsomeres that would make this a male. See for more info

 
Based on your image and looki
Based on your image and looking at mine more closely I'm sure you are correct. (The expanded front tarsomeres were slightly out of focus which made them appear like larvae.) New camera shows more detail than old one but you still have to get a good shot to the fine details. Are these expanded front tarsomeres like brushes or fine hairs?
Did you mean to say you "liked" my images or did you link them to something or each other in some way?

 
I linked all three together, because they are all of the same individual. You can see how to do that here

As for the front tarsomeres, I really can't say, I don't know these guys well enough.
