Two species of Ash-leaf Aphis
are
Prociphilus bumeliae & Prociphilus fraxini
and they are identical at this stage.
Both of these species are host alternate. - From Ash (Fraxinus) to Fir (Abies)
Apparently the wax protects the aphids from the effects of their own honeydew. Also it is thought they tend to stop producing honeydew when , as in this case, they are attended by ants.
JE a took a sample and determined these were
Prociphilus bumeliae
AshLeaf Aphid
Only the winged individuals (alates) are capable of being determine but still tricky if not impossible from photographs.
You need to be able to determine the relative lengths of the third antennal segment as compared to the second.
