This was a mating pair, which split up before I could start photographing them.

They look pretty much like ordinary green stink bugs, except that (1) they're very small, and (2) they have a thin band of reddish color stroked side to side across the middle of the pronotum.
Here they are shot against 1 mm grid paper. The first one is the same individual seen on the left above, so clearly the black band behind the head is just a transient gap between head and prothorax .


I've been finding these things on my raspberry plants. I have no idea what they eat; that's just where I find them.
My plan is to submit them to BugGuide.net for ID, but mostly for amusement I'm also posting here.
The amusement begins with the fact that these things are not inclined to stand still to be photographed, and they have only a little hesitation about taking flight. Fortunately I was able to bat the escapee out of the air before it got lost.
So then I figured "You know what? These are summer beasts. All I need to do is cool them down."
So I stuck their box in the refrigerator overnight, then to make Really sure that they didn't get away from the camera, I moved them onto a raspberry leaf that was floating on some very cold water, surrounded by floating ice cubes. That explains the water you can see in the first photo.
Here's the setup:

But what, you ask, could possibly be amusing about this?
Well...

Apparently these things have quite a wide range of acceptable operating temperatures. It was 104 F outside today. Coming out of a refrigerator and walking across an ice cube, no problem.
Color me impressed. Also humbled. Sigh...
