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
Green-head ant myrmecophilous insects such as the beetle "Chlamydopsis longipes" are sometimes seen living inside colonies. Green-head ant males are produced irregularly throughout the year and are low-flying ants. Recorded nuptial flights begin between September to November at temperatures of 20–25 °C (68–77 °F), when a number of males begin to emerge from their nest. Sometimes, however, the males may return to their nest after briefly appearing outside. The green-head ant is a gamergate species, which means that males can successfully mate with the workers. These workers remain outside their nest with their head and thorax appressed and gaster elevated into the
