Bird Chery Oat Aphid
Moved from ID Request.

Good call, Derek. "Winged adults have black heads and thoraxes and green abdomens." Goofy common name, though :)
Thanks, Robert

Not goofy at all :-P
Their primary host is bird cherry, with their secondary hosts being various grasses, especially oats and wheat.

Oh, it's the lady with the pretty smile
Bird Cherry Oat Aphid sounds like a ceral :)) I like Oat-Birdcherry Aphid better With the cold weather, I'm photographing things that might otherwise be "targets of opportunity." I think this ID answers several of my unknown aphids.

Probably.
This time of year lots of grain aphids are out. Mostly this one and the closely related corn-leaf aphid Rhopalosiphum maidis :) You can tell them apart by that last thin segment on the 6th antennal segment (it's longer on R. padi) and the shape of the cornicles. R. padi has a 45° at the end, but R. maidis has barrel-shaped cornicles.
