Oooooo a mystery....

Yes it is an aphid, and something in Eriosomatinae. The only two genera I can think of with a once-branched m-vein are Eriosoma and Pachypappa. I don't think Eriosoma would be 10mm. Is that including the wings or just the body length? Eriosoma are generally around 1-3mm BL but I've seen some huge Pachypappa, and they're described as up to 5mm BL. Tough to decide in pictures since normally I'd also look at siphunculi (poriform in Eriosoma, absent in Pachypappa) and sensoria (annular in Eriosoma, oval to oval transverse in Pachypappa).

Thank you for sharing your an

Thank you for sharing your analysis. I understand that this is not an easy case without having the critters in hand. When it comes to size, I do not know it's the same thing for insects as for birds, but in the case of birds, it's common for individuals of the same species living further north to be bigger. than their southern counterparts. This would be caused by the harsher conditions that prevail further north. For example, the American Crow, individuals from the North can be up to twice as big as those from the South.

Some aphid species are just really variable.

I’ve collected hundreds of specimens from the same colony, and found individuals that are twice as large as others. Different morphs can also be super variable, egg laying and live birthing morphs( for example) aren’t even identified as the same species sometimes. 😂 There is still a lot we don’t know about aphids.

Seems as though it has to go here. Natalie will let us know if I'm wrong. :)
