Gray Aphids - Uroleucon rurale

Moved

Moved from Uroleucon.

Helps that I now know U. rurale is green with dark appendages and U. verbisinae is black or red.

Probably Uroleucon

I can't see the right characteristics to be positive, but the dark siphunculi, dark cauda, and general shape make me think Uroleucon. Not many aphids are observed feeding on Verbesina and the only other one that would look similar at all is Macrosiphum euphorbiae which wouldn't have a dark cauda or siphunculi. U. rurale or U. verbesinae are the two species that would have dark siphunculi and a dark cauda, but you'd have to look at the rostrum to distinguish between the species, although U. rurale is listed as occuring in your area and U. verbesinae usually occurs further south. U. verbesinae is also described as "shining bright red or black". So perhaps this is U. rurale after all. I'm done babbling now.

Thanks,

Natalie, I do understand babble fairly well!
