I've just looked into the flower which seems to be Tanacetum vulgare.
Tanacetum vulgare is an Asteraceae flowering plant.

based upon this information, the species should be Chaetostomella cylindrica.
yet it looks most like Chaetorellia jaceae which is very odd.

I think about aphids: a dogwood aphid's host plant is dogwood but I see it on many plants when it moves around. I've seen it on nettle. Thus I wonder if it is possible to see C. jaceae on a different plant?
