There were thousands of these covering the upper leaves of Cup Plants (Silphium perfoliatum)which is a tall prairie plant. Every Cup Plant had them, but they didn't seem to be on any other plant species. Some seem to have wings. ID?

Aphids
They are aphids. A mixed of winged and wingless aphids on a plant stem is a common sight. Your host plant ID might allow aphid species ID; I don't know much about the family. (A web search suggests genus Macrosiphum.)

Uroleucon sp.
This must be one of the many red Uroleucon species that specialize in Asteraceae. I found some old references that say "Macrosiphum" (now Uroleucon) rudbeckiae feeds on Silphium, but a more recent source only mentions this species feeding on Rudbeckia. I haven't found a modern reference naming the species that feeds on Silphium, so moving to genus for now.
