Termite
Isoptera
Quick answer
Termites are small, social insects that live in large colonies and feed mainly on dead plant material such as wood, leaf litter, and soil. They are ecosystem engineers that recycle dead wood and enrich soils, though a few species are serious pests of timber buildings. Colonies are organized into castes around a king and queen, and some queens can live for many years and lay enormous numbers of eggs.

Where it lives
Soil and wood in tropical and warm-temperate regions worldwide; ecosystem engineers that recycle dead plant matter.
Life in the colony
Termites live in highly organized colonies divided into castes, with workers, soldiers, and a reproductive king and queen. Workers gather food, build and repair the nest, and care for the young, while soldiers with large heads or jaws defend against predators such as ants. A single colony can contain from a few thousand to several million individuals.
Diet and digestion
Termites feed mainly on dead plant material, especially the cellulose in wood, leaf litter, and dry grass. Because cellulose is hard to digest, many termites rely on microbes living in their guts to break it down, while others cultivate fungus gardens for the same purpose. This ability lets them recycle huge amounts of dead plant matter.
Ecosystem engineers
By breaking down dead wood and plant litter, termites return nutrients to the soil and help shape entire ecosystems. Their tunneling aerates and mixes the soil, improving its ability to hold water, and some species build towering mounds that can stand for decades. In many tropical regions termites are among the most important decomposers.
Termites and people
While most termite species are harmless or beneficial, a small number feed on the wood in buildings and can cause significant structural damage. These pest species are the reason termites have a reputation for destruction, even though the majority play a positive role in nature. Effective control focuses on protecting timber and detecting infestations early.
Frequently asked questions about the Termite
What do termites eat?
Termites feed mainly on dead plant material, especially the cellulose in wood, leaf litter, and dry grass. Microbes in their guts or cultivated fungus help them digest this tough material.
Are all termites pests?
No. Only a small number of termite species damage buildings, while most live in soil or dead wood and play a valuable role recycling nutrients. The pest species, however, can cause serious structural damage.
How long do termites live?
Worker termites usually live a few months to a couple of years, while queens are exceptionally long-lived, with some surviving for many years and laying eggs continuously.
Why are termites important?
Termites recycle dead wood and plant litter, returning nutrients to the soil and aerating it through their tunneling. In many ecosystems they are among the most important decomposers.
Do termites have a queen?
Yes. A termite colony centers on a reproductive king and queen, with the queen laying most or all of the eggs. Sterile workers and soldiers carry out the colony's other tasks.
What is the difference between termites and ants?
Although both are social insects, termites are more closely related to cockroaches than to ants. Termites have straight antennae and broad waists, while ants have elbowed antennae and narrow, pinched waists.
