The species also known as Nitrogen fixing species that can help the soil be rich, so besides the important role on Carbon cycle of the ecosystem, they also are one of a key species of Nitrogen cycle in tropical forests.

The nest of the species can easily recognized on the ground with size quite large, some time reach to 0.7m about the ground.

Under the cover layer of the nest, there is a strong wall system and making the "skeleton" of the nest, they look like coral skeleton structure. Photographed by Cuong Do.

Because the nest of termite is quite stable condition so there are many other species can be found, they live in side some part of their life time or whole life. It is a safe place (protected by solder), good and stable conditions (temperature and humidity).
