Most colony members are progeny of the same parents. At initial stages of social evolution, individuals in a colony are uniform. For example, colonies of the tent caterpillar have no differentiation among individuals. Sociality is more advanced in bees, ants, and termites. They often have a division of labor and corresponding morphological differences.
Social insects have very complicated behavior.
Their success largely depends on coordinated actions of many individuals. For example, leaf-cutting ants have underground fungus gardens . Ants bring foliage to this garden and collect fungus for food. For example, lichen is a symbiotic organism formed from algae and fungi. I call symbiosis a heterogeneous metasystem transition because cooperation become established between different species of organisms.
