Colony Ontogeny and Social Organization
Weaver ant colonies are founded by one or more mated females (queens). A queen lays her first clutch of eggs on a leaf and protects and feeds the larvae until they develop into mature workers. The workers then construct leaf nests and help rear new brood laid by the queen. As the number of workers increases, more nests are constructed and colony productivity and growth increase significantly. Workers perform tasks that are essential to colony survival, including foraging, nest construction, and colony defense. The exchange of information and modulation of worker behaviour that occur during worker-worker interactions are facilitated by the use of chemical and tactile communication signals. These signals are used primarily in the contexts of foraging and colony defense. Successful foragers lay down pheromone trails that help recruit other workers to new food sources. Pheromone trails are also used by patrollers to recruit workers against territorial intruders. Along with chemical signals, workers also use tactile communication signals such as attenation and body shaking to stimulate activity in signal recipients. Multimodal communication in Oecophylla weaver ants importantly contribute to colony self-organization. Like many other ant species, Oecophylla workers exhibit social carrying behavior as part of the recruitment process, in which one worker will carry another worker in its mandibles and transport it to a location requiring attention.

Famous quotes containing the words colony, social and/or organization:
““Tall tales” were told of the sociability of the Texans, one even going so far as to picture a member of the Austin colony forcing a stranger at the point of a gun to visit him.”
—Administration in the State of Texa, U.S. public relief program (1935-1943)
“The one prudence in life is concentration; the one evil is dissipation: and it makes no difference whether our dissipations are coarse or fine; property and its cares, friends and a social habit, or politics, or music, or feasting. Everything is good which takes away one plaything and delusion more, and drives us home to add one stroke of faithful work.”
—Ralph Waldo Emerson (1803–1882)
“I will never accept that I got a free ride. It wasn’t free at all. My ancestors were brought here against their will. They were made to work and help build the country. I worked in the cotton fields from the age of seven. I worked in the laundry for twenty- three years. I worked for the national organization for nine years. I just retired from city government after twelve-and-a- half years.”
—Johnnie Tillmon (b. 1926)
