Lonomia obliqua is just as frail as any other caterpillar you might have seen, but that doesn’t stop it from causing severe serious internal hemorrhaging and even death by just a touch.
This terrible Lonomia caterpillar lives in the rainforests of South America and causes a few deaths per year. Mainly found in southern Brazil, they’re usually found on the bark of trees. Blending perfectly in their surrounding, Lonomia obliqua caterpillars often can’t be avoided, even if people watch out for them. Most incidents occur when travelers lean against a tree and unknowingly brush against one or more caterpillars, which release a very powerful anticoagulant venom.
Symptoms of Lonomia obliqua poisoning include severe internal bleeding, renal failure and hemolysis. If the skin comes into contact with several caterpillars, death is often the outcome.
