Black Willow Aphids

Black Willow Aphids
Amherst, Massachusetts, USA
May 23, 2004
Shot on a Dogwood sapling in our backyard. These field ants have been taking good care of them.

Possibly not black willow aphids
I'm trying to ID some aphids that look exactly like these, and I'm having no luck at all online. The aphids in this photo have all the right features (wingless, glossy black body, very short and light-colored cornicles, white stripes across the "shoulders"), but the photo on this specialist's site looks totally different.
