Any creature that threatens to eat your wood furniture and
structural1 beams presents a major problem. That's why a
termite2 infestation3 is usually cause for alarm, followed by chemical
extermination4. Yet
termites5 are as fascinating as they are potentially alarming. If you were able to shrink and
infiltrate6 a termite colony you'd notice four distinct groups: workers, soldiers,
immature7 individuals, and reproductives. The workers are the Cinderellas of the termite world; blind,
sterile8, and wingless, they tend the eggs, feed the soldiers and young termites, and maintain the nest.
Soldiers defend the colony from
predators9, the most dangerous being tribes of attacking ants. Although not as big and strong as their ant enemies, soldiers are equipped with an
arsenal10 of physical and chemical weapons. Some termites use sharp teeth to bite an attacker and then coat the wound with an anti-clotting chemical, causing the enemy to bleed to death. Other weapons include a paint-brush like device used to daub poison on enemies and a longish, hose-like snout used to spray
toxins11 on attackers.
Of the four groups, the reproductives might have the best job. Sealed off in a
chamber12 and tended to by workers, the one pair of active reproductive termites reproduce as often as possible. But the king and queen, as they are known, are more than just
pampered13 monarchs14. The queen, for one, is also a chemist. Alerted to the needs of the colony by her workers, the queen can
secrete15 chemicals that, when fed to the colony's adolescent termites, turn them into soldiers, workers, or future reproductives, as needed. In this way, the termite queen both propagates and protects her brood.
