Something I've seen that occurs in particular species of ants is a
peculiar behavior called "aphid farming" The ants will transport aphids
to suitable "grazing areas", then "milk" the aphids for "honeydew", an
aphid secretion rich in sugar. It might be a good idea to look closely
for aphids if ants are observed on the hop vines, and treat accordingly.
Ladybugs are hell on aphids, if you can convince them to hang around.
In any case, I'm not aware of any common species of ants that like to
chow down on hops.
