Coneflower problems

Asked July 8, 2020, 5:13 PM EDT

I have coneflowers in my northern cottage in the woods and everything is so dry here. I just noted some green blobs about 1-2 mm circular and slightly elevated with dark discoloration around them on my coneflower leaves and it is spreading to the others and the black eyed Susan’s. Is this a virus or an aphid infestation and what can i do about it? I depend on coneflowers so muc as nothing else really grows where I am. Thank you......
