Summary

Termites are social insects that play vital roles in their ecosystems as decomposers and soil engineers. They exhibit complex social behaviors and a caste system, which includes workers, soldiers, and reproductive individuals. Their relationship with humans can be both beneficial and detrimental, acting as ecosystems recyclers while causing significant damage to wooden structures worldwide.

Physical Characteristics

Termites are usually small, measuring between 4 and 15 mm in length. The largest queens can exceed 10 cm in length. Their bodies are soft due to a lack of sclerotization and often appear translucent; however, color and texture vary by species. Soldiers may have large heads with powerful jaws, while workers typically are wingless and blind.

Identification Tips

Termites can be identified by their moniliform antennae and the absence of eyes (in workers and soldiers). Winged reproductives, known as alates, are noted for their equal-sized fore and hind wings. The reproductive castes (king and queen) can be distinguished by their size and the swollen abdomen of the queen after mating.

Habitat

Termites inhabit diverse ecological environments on every continent except Antarctica. They can be found in dampwood, drywood, and subterranean environments, commonly nesting in wood, soil, or constructing mounds above ground.

Distribution

Termites widely distribute across nearly all global landmasses, with the highest diversity located in tropical regions, especially Africa, which has over 1,000 described species. They have been reported in low numbers in Europe and North America but are more diverse in South America and Australia.

Diet

Termites are primarily detritivores, consuming dead plant material, including wood, leaf litter, and faeces, which they digest thanks to symbiotic microorganisms in their gut. Some species also opportunistically feed on dead animals and have been known to practice fungiculture, cultivating specific fungi as a food source.

Life Cycle

Termites exhibit incomplete metamorphosis, starting as eggs that hatch into nymphs, which are immature individuals with visible wing buds before transforming into either winged adults (alates) or remaining as workers or soldiers. Workers undergo numerous molts throughout their life, showing significant developmental plasticity.

Reproduction

Termite colonies are founded by a monogamous pair of young alates (the king and queen) who mate and establish a nest. The queen lays 10-20 eggs initially but can produce up to 40,000 eggs daily at peak capacity. The caste system, including workers and soldiers, arises from ongoing larval development influenced by environmental factors and pheromonal cues.

Predators

Predators of termites include a variety of animals, notably ants, birds, centipedes, reptiles, mammals (e.g., aardwolves, anteaters), and some invertebrates such as spiders. Specialized ant genera perform organized raids on termite colonies, while some mammals and birds actively forage for termites.

Ecosystem Role

Termites are crucial ecosystem engineers, impacting soil formation, nutrient cycling, and decomposition processes. They are significant decomposers in subtropical and tropical regions, recycling vegetative material and contributing to soil health and structure.

Economic Impact

Termites cause significant damage to wooden structures and crops, leading to losses estimated in billions annually in regions like North America and Australia. They are also harvested as food in various cultures, providing a protein source.

Cultural Significance

Termites hold economic and cultural significance in various communities, being used as a food source, in traditional medicine, and as symbols in folk beliefs. In some cultures, termite mounds are regarded with spiritual reverence and are associated with indigenous practices.

Evolution

Termites are closely related to cockroaches and evolved from them, belonging to the order Blattodea. Molecular and morphological evidence suggests that termites and wood-eating cockroaches share a common ancestry.

Similar Taxa

• Blattodea
• Mantodea

Misconceptions

Termites are commonly referred to as 'white ants,' but they are not true ants and are distinctly different in evolutionary terms. Though sharing social behaviors, termites evolved their caste system independently from Hymenoptera.
