Rows of small bumps, each topped with a cluster of easily detached spines of different sizes1

Gifkrag

Brandhare

Piepklein haartjies of borsels breek in die vel af en brand.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

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

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

Wat doen dit as dit bang is?

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

As jy aan sy hare raak

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
Vir ruspe-brandhare: lig hulle af met kleefband en was dan die vel. Moenie vryf nie.
Vir byte: was en koel af. Kry mediese hulp as die persoon sleg voel of maklik bloei.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As jy aan sy hare raak: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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

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

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

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

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

Mite-breker

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

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