Anne Elliott's photos with the keyword: Willow Leaf Aphids?

This is the second really bad photo I'm uploading today - should have kept it to just one, lol! Does anyone know what insects these are? Are they Aphids? The one in the top right corner has wings. This is the underside of just a small Willow leaf, so these insects were really tiny. Macro photo taken at Maclean Pond, off Elbow Falls Trail (Highway 66), on July 21st.
