Ants (Order: Hymenoptera; Family: Formicidae) are highly social insects and are often associated in one way or another with plants. Ants sometimes form mutualistic relationships with plants, which may benefit from ant predation on plant herbivores or seed dispersal by ants. However, there are relatively few examples of pollination by ants. 

In some cases, ants actually appear to interfere with pollination, sometimes reducing plant reproductive output: they may consume nectar without providing the plant with any reproductive benefit; they are aggressive toward other insects, including pollinators; they can destroy floral tissue; and their secretions may reduce pollen viability.  Some plants appear to have evolved means of minimizing ant visitation to their flowers. In one example of ant interference with pollination, the ant, Crematogaster scutellaris, is a major predator of the fig wasp, which forms an obligate pollination mutualism with the Mediterranean fig tree (Genus: Ficus L.)

Borges, and M. Hossaert-McKey, In OIKOS, Volume 113, pages 344-352, 2006).
