While searching for plants that will attract more bees to the yard to help with pollination I saw this little blurb about ants, who knew?
"Pollination by
ants is relatively rare, but it does occur. Most pollinators can fly, enabling them to distribute pollen grains over a wider area, and thus promote genetic diversity among the plants they visit. Since ants walk from flower to flower, any pollen exchange conducted by ants will be limited to a small population of plants. In addition, ants produce an antibiotic called
myrmicacin, which is thought to reduce the viability of the pollen grains they carry. So overall, ants may not be the most effective pollinators.
Still, ant pollinators exist.
Formica argentea worker ants have been observed carrying pollen grains between flowers of Cascade knotweed (
Polygonum cascadense). Other species of
Formica ants distribute pollen among the flowers of elf orpine (
Diamorpha smallii, a compact herb that grows on granite outcrops. In Australia, ants pollinate several orchids and lilies effectively."
