Ecology
Its venom is not usually lethal to humans because it has arguably evolved to kill its prey by crushing it with its pincers and not by venom. This giant forest scorpion has often been seen around tropical rainforests and other types of moderately warm climates. Specimens are collected from inside degraded or semi-degraded termite mounds, tree holes and in abandoned rat or crab holes in the bunds of agricultural fields. Males are usually active during the summer season from April to July. Solitary individuals come out of their dens during that period. References
