Maybe Macrosiphum
Some of them can be waxy like this and also have green and pink forms. I think I see a constriction at the tip of the siphunculi which would support that, but its hard to see. This also looks like a nymph, which don't have a lot of the characters used for ID, because keys and descriptions are based on adults who have more developed siphunculi, caudas, antennae, etc.

Thanks. I have added a photo of what I believe is an adult from the same group. If that is not enough I will try to get some better photos.

Is there a tulip tree nearby?
The adult pic is great, but the siphunculi make me think Illinoia, and a common one is Illinoia liriodendri.

Yes, there are a number of tulip trees in the area – after a storm the blossoms and leaves litter the path.

Sweet!
Then I am pretty sure that’s what they are. I don’t know of this species having a pink form, but Macrosiphum euphorbiae does, and has also been recorded on Tulip tree.

Great! Thanks. I'll see if I can get a shot of the pink ones.
