A typical envenomation incident involves a person unknowingly leaning against, placing their hand on, or rubbing their arm against a group of these caterpillars that are gathered on the trunk of a tree. The effects of a dose from multiple caterpillars can be dramatic and severe, including massive internal hemorrhaging, kidney failure, and hemolysis. The resulting medical syndrome is sometimes called<unk> sis. Death may result, either rapidly or after many days following envenomation. The of the<unk>  venom is 0.19 mg for an 18–20 g mouse (IV); however, due to the small amount of venom in the bristles of the caterpillar, the rate of human fatality is only 1.7%. While there are more than a dozen species in the genus, the most troublesome species is<unk>  obliqua, and it is this species on which most of the medical research has centered. As anticoagulants have some very beneficial applications (e.g., prevention of life-threatening blood clots) the research is motivated by the possibility of deriving some pharmaceutically valuable chemicals from the toxin.
