sorry farm1,

you maybe a bit off the mark there, ants not only have a symbiotic
relationship with sacle insects but also with mealy bugs and aphids
pretty much any thript. and aphids do secrete a sugary substance
that
the ants use in their food chain.

Well I can only say that I have never seen an ant near the aphids on
my roses. And my garden has multiple varieties of ants. Perhaps the
wrens clear the aphids before the ants have a chance to find the
aphids.

the aphid is flightless and can't crawl over the ground so the only
way it gets around is by being carried.

Wrong Len. Aphids do grow wings. See
