Green shield bug

This bug, and several others, were anything but camouflaged as they meandered around the bright red autumn leaves of the Rhus Sumac. I think it's a common green. There are some Echinaceas underneath the Sumacs and spotted another shield bug on one of the flowers. I've tried to ID it, but it's not one of Google's top 10 shield bugs, so, any blipping shield bug experts, please ID the bug in extras. Thank you.
