Termites are super-social insects with a crypto-biotic behavior (well hidden). Here in Connecticut the termite of most importance is the Eastern Subterranean Termite. This termite travels in the soil in search of a food source. It builds mud tubes when leaving the soil to stay protected from the elements. There are 3 castes in the colony, the worker, the soldier and the reproductive. Here are some interesting websites about Eastern subterranean termites.
