1. Termite

Termites, part of the order Blattodea, are eusocial insects found worldwide, thriving in warm, humid climates. Measuring 0.1–0.6 inches (2.5–15 mm), their caste-based society includes workers, soldiers, and reproductive alates (future queens and kings). Workers are pale and wingless, soldiers have large jaws for defense, and alates are winged during swarming.

They feed on cellulose-rich materials like wood and plant debris, using gut microorganisms to digest cellulose and sharing food via trophallaxis. Colonies are highly organized, with workers maintaining the nest and soldiers protecting it. Queens and kings reproduce continuously, while workers care for eggs and larvae. Termites play vital ecological roles by recycling nutrients but can also cause structural damage.
