Termites are social insects traditionally placed in the group Isoptera. They live in colonies organized into castes and feed largely on cellulose found in dead wood, leaf litter and other plant debris. Although commonly called "white ants," termites are not ants and belong to a different evolutionary lineage, with distinct morphology and behavior.

Characteristics and appearance

Individuals vary by species but typically have soft bodies, chewing mouthparts and, in reproductive stages, two pairs of similar wings. Workers perform most nest maintenance and feeding tasks, soldiers defend the colony with specialized heads and mandibles, and reproductives (including winged alates) enable dispersal and colony founding. Some species maintain multiple egg-laying queens while others have a single primary queen.

Social organization and life cycle

Termite societies meet the criteria of eusociality: cooperative brood care, overlapping generations and division of reproductive labor. Development proceeds through a series of nymphal instars rather than complete metamorphosis; individuals may change caste during growth in response to environmental cues and colony needs. Reproductive adults swarm seasonally, pair off, shed their wings and establish new nests.

Ecology and geographic distribution

Termites are especially numerous and ecologically important in tropical and subtropical regions, where they act as major decomposers of cellulose and play a key role in nutrient cycling and soil formation. Their tunneling and feeding change soil texture and water movement. Some species build large, architecturally complex mounds that regulate temperature and airflow and can persist for decades.

Economic importance and management

While most termite species are harmless components of natural ecosystems, a minority damage human property, wooden structures, crops and plantation forests. Management approaches include preventive building practices, sanitation, physical and chemical barriers, targeted baits and integrated pest management. Accurate species identification is important because biology and effective treatments vary among termite groups.

Notable distinctions and facts

  • Termites differ from ants in wing vein pattern, waist constriction and social evolution; they are often mistaken for ants because of superficial resemblance.
  • Estimates put the number of species in the low thousands; many remain understudied, especially in tropical forests.
  • Mound-building species influence landscape ecology and provide habitats for other organisms.
  • Colony behavior demonstrates coordinated activity often discussed under swarm intelligence and collective systems.
