Abstract: In southern Brazil, since 1989, several cases of accidents produced by unwilling contact with the body of poisonous caterpillars of the moth species Lonomia obliqua Walker, 1855 (Lepidoptera: Saturniidae), were described. L. obliqua caterpillars have gregarious behavior and feed on leaves of host trees during the night, staying grouped in the trunk during the day, which favors the occurrence of accidents with the species. This caterpillar has the body covered with bristles that on contact with the skin of indi… Show more

“…The clinical record and physical examination are essential factors for an adequate diagnosis. Patients usually consult after a not very long period of evolution after the contact with the larva of L. obliqua (28,29), reporting a clinical picture of malaise associated with burning pain at the contact site, myalgia, and occasionally high temperature, which is usually accompanied by hemorrhagic systemic manifestations (gingivorrhagia, epistaxis, ecchymosis and even digestive hemorrhages) (8,15,17,30). In some very severe cases there may even be intracerebral hemorrhage.…”

“…Larval lepidopterans (caterpillars) use venom to deter predators. The chief symptom of envenomation is pain and/or irritation, though some caterpillar envenomations of humans are capable of causing numbness, vomiting, respiratory paralysis, and even death (Kawamoto and Kumada, 1984;Balit et al, 2003;Hossler, 2010;Maggi and Faulhaber, 2015).…”

“…Venom has additional actions on vascular muscle cells, inducing proliferation and migration that may contribute to haemorrhage (Moraes et al, 2017). Several recent reviews provide a comprehensive overview of Lonomia venom (Carrijo-Carvalho and Chudzinski-Tavassi, 2007;Alvarez-Flores et al, 2010;Maggi and Faulhaber, 2015). Zygaenoidea (venomous lineage 10, Fig.…”
