[net.garden] Maple Trees

I know it is almost time for the leaves to fall off my maple trees,
but they ARE supposed to turn yellow first, aren't they?  The leaves
were dropping at a tremendous rate.  What's more I noticed literally
thousands of bees, wasps and flies on the leaves, both on the tree and
on the ground.  Upon closer inspection I noticed tens of thousands
of aphids on the leaves ( well, not all on one leaf, that would be
pretty crowded).  I sprayed the trees with safers insecticidal soap.
It is 'natural' in that it really is just soap, but it is supposed
to get rid of the aphids.

Am I right to assume the leaves were falling off because of the damage
from the aphids?  And that the bees and such were enjoying the sugar sap
the aphids caused (much like ants do)?
