[1] Important coagulation factors are activated by the specific serine proteases in the venom and as they become exhausted, coagulopathy develops. Symptoms are consistent with uncontrolled bleeding.
Larva of Lonomia obliqua, the most toxicologically-significant species, to mammals, of its genus; stings are a medical emergency and require treatment with antivenom. Several lepidopteran families include species whose larvae bear urticating hairs. Families prominent in this respect include the following: [2] [3] [4] [5]
Antivenom, also known as antivenin, venom antiserum, and antivenom immunoglobulin, is a specific treatment for envenomation.
