Caterpillars of many species can cause irritation by their hollow body hairs that envenom or detach easily, or can be poisonous if ingested. [5] Prior to investigations into Lonomia caterpillars, it was not known that caterpillars could produce toxins in sufficient quantities to kill a human.
Hairs from the caterpillars are toxic for humans, [5] causing a poison ivy-like itchy rash of up to sometimes weeks-long duration due to mechanical and chemical irritation. [6] [7] Direct contact with larvae is not necessary, as the hairs are shed and can become windblown. [5] Toxins in the hairs remain potent for up to three years.
