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 spider and use their mimicry to enter and leave the nest unmolested (if the ants detected them as intruders they would mass to repel and perhaps kill them). The spiders walk on only the three rear pairs of legs, and if they encounter an ant during their forays into the nest territory, they touch their front legs to the ant's antennae in the same way as another ant would with its own antennae. If they have already captured an ant, they then offer that towards the challenging ant, which inspects it and behaves towards the spider as if it were another
