Plant-parasitic Hemipteran

ForestDragon if I hesitated, I'm sure you would have figured it out soon. I have the advantage having seen these multiple times:-)

becantor, thanks for sharing these beautiful little insects! I agree with Tom for the ID.

I've never seen them before. I spent quite some time figuring out what they were and Tom, you beat me out for the ID suggestion by less than a minute! haha!

Nice find! All the ones I've found have been on winged sumac leaves.
