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

Finally, in 1930, with Ivan Pogosski leading, actual work was started on the aircraft. Its first flight was on January 30, 1931, piloted by S. Riballschuk. It is important to note that shortly after the ANT-8 flew for the first time, the ANT-14 lifted off
