Pharaoh ant site. Pharaoh ant colonies appear to prefer familiar nests to novel nests while budding. This suggests the ability for colonies to remember certain qualities of their living space. However, if the novel (unfamiliar) nest is of superior quality, the colony may initially move toward the familiar, but will eventually select the unfamiliar. The colony assumes the familiar nest is preferable, unless they sense better qualities in the novel nest. This decision-making process seeks to minimize the time the colony is without a nest while optimizing the nest the colony finally chooses. The number of available budding locations has a large
Myrmecia (ant) If a nest is disturbed, a large force of workers rapidly swarms out of their nest to attack and kill the intruder. Some species, particularly those of the "M. nigrocincta" and "M. pilosula" species groups, are capable of jumping several inches when they are agitated after their nest has been disturbed; jumper ants propel their jumps by a sudden extension of their middle and hind legs. "M. pyriformis" is considered the most dangerous ant in the world by the "Guinness World Records". "M. inquilina" is the only species of this genus that is considered vulnerable by the IUCN, although the
