It is hard to predict what form a larvae will turn into or what role it will play. The only sure thing about termites is they can transform into various parts of the caste to build the colonies for their ever evolving requirements - King, Queen, Soldiers, Workers and Reproductives.
For instance, if the colony is in need of more workers, a Nymph begins going through a sequence of reversions and become a False Worker. Once a reproductive termite reaches full maturity, it leaves the nest; then it develops wings, functioning eyes, darker/harder bodies (assisting in withstanding light and less humid air), and starts a procedure called as swarming.
Swarming happens as the termites decide to spread out their territory. Thousands of reproductive termites may leave the nest to develop new colonies. The swarmers (termites that involve in swarming) will finally shed their wings while reaching their destination and can never fly again.
