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
Erratic ant nest structure to concentrate solar heat onto the ants' brood. Nuptial flights take place in June, although they may be postponed during colder years to July. Erratic ant The erratic ant ("Tapinoma erraticum") is a species of dolichoderine ant first described in 1789 by Latreille. This species ranges throughout Central Europe from the mountains of south Italy to north Germany. It is present in coastal areas of Southern England and on the islands of Gotland and Öland in Sweden. A thermophilic species, "T. erraticum" is found principally on dry heathland, exposed to the sun. The workers are very agile, and
