Never Touch This Caterpillar

Описание: This documentary explores Lonomia obliqua, the “killer caterpillar” responsible for some of the most unusual and dangerous poisoning cases in modern medical history. We follow how this seemingly ordinary moth larva, found in parts of Brazil and other regions of South America, became a focus of intense scientific and clinical investigation after people who brushed against it began suffering unexplained bleeding, organ failure, and, in some cases, death. Through historical case reports, hospital records, and interviews from the early outbreaks in the 1980s and 1990s, the video traces how physicians slowly connected scattered incidents of hemorrhage to a venomous caterpillar hiding in plain sight.

Alongside the medical story, the video looks at how Lonomia’s venom works, why its spines are so dangerous to human blood clotting, and how researchers developed an antivenom that changed the outcome for patients in rural communities. By placing this insect within the broader history of venom research and toxicology, the episode shows how an obscure forest species became one of the most medically important venomous insects in the world, reshaping our understanding of contact venom, environmental risk, and human encounters with hidden dangers in nature.
