Aphid on Cannabis - Phorodon cannabis

Aphid on Cannabis - Phorodon cannabis
Grants Pass, Josephine County, Oregon, USA
February 8, 2019
Photos taken of aphids on Cannabis in a Greenhouse, temps averaging 60*F, humidity 70-80%, resembling what I believe could be Phorodon cannabis (3 stripes plus horn like appendages and fairly long cornicles). Based on this ODA pest alert https://www.oregon.gov/ODA/shared/Documents/Publications/IPPM/CannabisAphidAlert.pdf, I'm thrown off by it being more brown and not yellow/green. Shown next to what is probably Myzus persicae for scale. Any ideas?

Yes, Phorodon cannabis
You are correct, the genus is pretty distinct because they have those finger-like projections coming off the top of their head plus the three dorsal stripes. I don't think any of them are Myzus, which would not have that noticeable fuzzy appearance (capitate setae), I think they are just different color morphs and the lighter ones are earlier instars. I have seen some other cannabis aphids turn pretty brown or they could be parasitized which discolors them.

Here are some images for comparison.

Moved to Aphididae for expert attention.
Moved from ID Request.

Aphids are tough to ID from photos, but with luck Natalie will be able to take the ID further.
