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
Ant from other social insects including other ants. Some species specialise in preying on termites ("Megaponera" and "Termitopone") while a few Cerapachyinae prey on other ants. Some termites, including "Nasutitermes corniger", form associations with certain ant species to keep away predatory ant species. The tropical wasp "Mischocyttarus drewseni" coats the pedicel of its nest with an ant-repellent chemical. It is suggested that many tropical wasps may build their nests in trees and cover them to protect themselves from ants. Other wasps, such as "A. multipicta", defend against ants by blasting them off the nest with bursts of wing buzzing. Stingless bees
