Meat ant within a colony is typically favoured as it improves access to forage, as workers deliver most of their food to the nest that is closest to any site they forage in. At any size, a meat ant nest always has a possibility of dying out in any year, but the site may be reoccupied by another colony. Hence, nests can be very old as suggested in one study. Some nests may never be reoccupied for unknown reasons. The regrowth of vegetation which shades the nest, soil damage or even a disease may wipe out a colony and leave the nest
Weaver ant Weaver ant Weaver ants or green ants (genus Oecophylla) are eusocial insects of the family Formicidae (order Hymenoptera). Weaver ants live in trees (they are obligately arboreal) and are known for their unique nest building behaviour where workers construct nests by weaving together leaves using larval silk. Colonies can be extremely large consisting of more than a hundred nests spanning numerous trees and containing more than half a million workers. Like many other ant species, weaver ants prey on small insects and supplement their diet with carbohydrate-rich honeydew excreted by small insects (Hemiptera). Weaver ant workers exhibit a clear bimodal
