Ant (Dolichoderinae) are known to selectively grow species of epiphytic "Squamellaria" (Rubiaceae) which produce large domatia inside which the ant colonies nest. The ants plant the seeds and the domatia of young seedling are immediately occupied and the ant faeces in them contribute to rapid growth. Similar dispersal associations are found with other dolichoderines in the region as well. Another example of this type of ectosymbiosis comes from the "Macaranga" tree, which has stems adapted to house colonies of "Crematogaster" ants. Many tropical tree species have seeds that are dispersed by ants. Seed dispersal by ants or myrmecochory is widespread and
Little black ant Little black ant The little black ant ("Monomorium minimum") is a species of ant native to North America. It is a shiny black color, the workers about 1 to 2 mm long and the queens 4 to 5 mm long. It is a monomorphic species, with only one caste of worker, and polygyne, meaning a nest may have more than one queen. A colony is usually moderately sized with only a few thousand workers. "Monomorium minimum" are scavengers that will consume anything from bird droppings to dead insects. They are predators of codling moth larvae, and also of fall webworm.
