Size: 1mm or less
Someone brought some pink roses from there garden into our office and as people went to smell them someone noticed some tiny bugs on the peddles. I ran to get my camera and macro lens and took a few pictures. Someone said they were mites, and I thought they looked more like Aphids but wasn't sure.

Moved from Potato Aphid. I think I didn't know about M. rosae when I moved this. They look the same to me, and both feed on rose. I haven't been able to find information on how to distinguish them.

Moved from Aphids.

Could they be
M. rosae instead? How was this ID determined?

Yes, aphids.
Usually tough to ID past that. You're smart to include host plant info, as that can help greatly. "Tail pipes" are an easy to tell these are aphids.

Thank You
Confirmed!! Thanks again. I will remember the "Tail pipes" That's easy to remember. ;)
