Kalotermes flavicollis, the 'Yellownecked dry-wood termite', is a species of 'Dampwood termites' belonging to the family Kalotermitidae, one of the most primitive families of termites.
Subterranean Termites belong to the family Rhinotermitidae. This species lives in the soil and builds the largest nests of any insect in the U.S. These nests are connected via mud tubes to food sources, such as trees, fence posts and structural timbers in houses. Subterranean termites, which can live in every U.S. state except Alaska, are responsible for the majority of termite damage in this country.
The Serritermitidae family is very similar to the family Rhinotermitidae which are the subterranean termites. They prefer to create nests with contact to the soil. There is a single species in the world.
Dampwood termites constitute a small and rather primitive family Termopsidae (Latin) of termites (Isoptera). They contain four or five extant genera with 13–20 living species, but can be divided into several subfamilies.
