Ho e tseba jwang

  • Background colour ranges from green to brown, which helps it blend in1
  • Rows of small bumps, each topped with a cluster of easily detached spines of different sizes1

Chefo ya yona (eo e e kenyang ka ho loma kapa ho hlaba) e etsang?

The venom is held in sacs at the base of each spine and flows through the hollow spines into the wound. It causes disseminated intravascular coagulation, which stops the blood from clotting and leads to bleeding into the tissues and internal organs. After an initial phase of headache, fever, vomiting and malaise, a severe bleeding disorder can develop after about 24 hours.1

The caterpillar has been responsible for at least 500 deaths. In Brazil, 42,264 accidents were recorded between 2007 and 2017, of which 248 were severe and five were fatal. The reported death rate is 2.5%. Most victims were male (63%), and 45% were between 0 and 21 years old.1

E etsang ha e tshohile?

Its body is covered in hairs and spines that break off easily and inject venom into anything that touches them.1

Haeba o ama boya ba yona

  • A study by Dr Robert Norris states that stings and abrasions should be treated with antifibrinolytics. If blood products are needed, they must be given with care so they do not worsen the bleeding. An antiserum made by the Butantan Institute in São Paulo reverses the clotting problems, and patients treated with it recover quickly.1

Dintlha

1

Guinness World Records lists it as the most venomous caterpillar in the world.1

2

Before studies of Lonomia caterpillars, it was not known that caterpillars could produce enough toxin to kill a person.1

3

Its venom contains anti-clotting agents that have been studied for possible medical uses, including a component called Lopap.1

4

The first known epidemic happened in an farming community in Rio Grande do Sul, where victims had only handled leafy branches before their symptoms began.1

5

Only two of the 26 Lonomia species found in the Americas, L. obliqua and L. achelous, have caused severe reactions.1

Ho senya ditshomo

Tshomo: Caterpillars cannot produce toxins strong enough to kill a person.

Nnete: This caterpillar's venom can kill. At least 500 deaths have been linked to it.1
