The caterpillar is regarded as a dangerous insect because of its venomous spines. Exposure to the caterpillar's fur-like spines will lead to an immediate skin irritation characterised by a, "grid-like hemorrhagic papular eruption with severe radiating pain". The pain has been described by patients as similar to a broken bone or blunt force trauma.[1] The reactions are sometimes localized to the affected area but are often very severe, radiating up a limb and causing burning, swelling, nausea, headache, abdominal distress, rashes, blisters, and sometimes chest pain, numbness, or difficulty breathing.[4] Additionally, it is not unusual to find sweating from the welts or hives at the site of the sting.
