Termites have a caste system, i.e. each member of a group has a different responsibility within the group. Also every "caste" is characterized differently from another by its overall body structure. The most common castes are usually workers, soldiers, kings and queens. Only the kings and queens are able to reproduce.
Termite workers and soldiers are not able to reproduce. Termites are usually pale and soft-bodied. They are having small antennae. The workers and soldiers might be either male or female. Worker termites keep strong jaws for chewing wood or other eating stuff. Depending on the species, soldiers may have huge heads with sharp, power jaws or smaller, pointed heads. They tend to be taller and have thick bodies than the workers.
So far as wings are concerned, only the insects that are able to reproduce i.e. lay eggs have wings. The wings are the same size. Termites usually keep their wings rest over the body when resting. Queens often have bloated, sausage-shaped abdomens. Queens range in length from 2 to 4 inches. While Larvae or young termites, look like the adults.
