Social Organization
At maturity, a primary queen has a great capacity to lay eggs. In species, the queen adds an extra set of ovaries with each resulting in a greatly distended abdomen and increased fecundity often reported to reach a production of more than 2,000 eggs a day. The distended abdomen increases the queen's body length to several times more than before mating and reduces her ability to move freely, though attendant workers provide assistance. The queen is widely believed to be a primary source of pheromones useful in colony integration, and these are thought to be spread through shared feeding trophallaxis.
The king grows only slightly larger after initial mating and continues to mate with the queen for life (a termite queen can live for 45 years). This is very different from ant colonies, in which a queen mates once with the male(s) and stores the gametes for life, as the male ants die shortly after mating.
The winged (or "alate") caste, also referred to as the reproductive caste, are generally the only termites with well-developed eyes, although workers of some harvesting species do have well-developed compound eyes, and, in other species, soldiers with eyes occasionally appear. Termites on the path to becoming alates going through incomplete metamorphosis form a subcaste in certain species of termites, functioning as workers "pseudergates" and also as potential supplementary reproductives. Supplementaries have the ability to replace a dead primary reproductive and, at least in some species, several are recruited once a primary queen is lost.
In areas with a distinct dry season, the alates leave the nest in large swarms after the first soaking rain of the rainy season. In other regions, flights may occur throughout the year, or more commonly, in the spring and autumn. Termites are relatively poor fliers and are readily blown downwind in wind speeds of less than 2 km/h, shedding their wings soon after landing at an acceptable site, where they mate and attempt to form a nest in damp timber or earth.

Famous quotes containing the words social and/or organization:
“Despair, feeding, as it always does, on phantasmagoria, is imperturbably leading literature to the rejection, en masse, of all divine and social laws, towards practical and theoretical evil.”
—Isidore Ducasse, Comte de Lautréamont (1846–1870)
“In any great organization it is far, far safer to be wrong with the majority than to be right alone.”
—John Kenneth Galbraith (b. 1908)
