Thanks for the ID. I saw on this page: https://aphidtrek.org/?page_id=219 that they can be found on Rubus parviflorus, but I found these on Rubus spectabilis. Are they just fond of Rubus in general?

 
Just those two.
The preferred host of this species is Rubus parviflorus, but it has been previously recorded on Rubus spectabilis as well (see links below). It has not been recorded on any other Rubus spp. It is not really unusual to find certain monoecious species on closely related plants, and I've also seen some aphids on species not even closely related to their usual hostplants.

Wow that's a cool site. I've never seen a page that lets you reverse look up the species by host plant. Thanks!

 
Best Site for Aphids
It was originally three books, but they added all the information online and it is updated from time to time, unlike the books.

There is also this one based in Europe, but it has a lot of the same species in North America, and some really great pictures.
