Default Blasted blackfly

Bad infestation on annual cosmos and venidium, but none on dahlias planted
in same bed here in midlands , weird?
No sign of any greenfly or whitefly at all, except very early in spring.
Perhaps late coolness in spring, coupled with loadsa rain kept green/white
fly down in breeding season, perhaps dahlias have had time to harden up
before the green/white fly have attacked. Just a theory.

Our Dahlia excelsa (present from David Hill) has had a real blackfly
attack.
I was walking past it this afternoon and saw twisted and 'sad' leaves and
then, further up this very tall Dahlia, several stems and leaves infested
with the critters. I don't remember it suffering like this before and as
there are loads of sparrows nesting in the eaves above it, I think the
ungrateful little devils better get to work!
Ray has sprayed it with an organic spray, so we will inspect again
tomorrow.
Is this a particularly bad year for blackfly in others' gardens?
