This species has soldiers with large yellowish heads and bright black, asymmetric, snapping mandibles; it feeds on very rotten wood in contact with soil. Interestingly, it has been shown that a crocodilian species (Paleosuchus trigonatus) that lives in rainforest streams [...]

Termites of the Amazon rainforest – part 2

Termite quantification is generally difficult because of their discontinuous distribution, i.e. populations are structured in familial groups, the colonies. Besides, they remain hidden most of the time. Last but not least, termites are often difficult to identify by external morphological characters only. On the other hand, some species build conspicuous structures, which helps in both [...]
