The Chilean recluse is a brown spider from South America that is considered the most dangerous of the recluse spiders. Its bite can cause serious skin damage and, in rare cases, serious illness that affects the whole body. It is also known for spreading to homes and buildings in several other countries.1

Kako ga prepoznati

Brown, ranging from light tan to brown.1
Usually has a dark, violin-shaped marking on the top of the front body section, but this marking may not be visible.1
Has six eyes arranged in three pairs, not the eight eyes most spiders have. Checking the eyes is more reliable than checking the marking.1
Measures 8 to 40 mm including legs, making it one of the larger recluse species.1
Builds irregular webs with a messy shelter of tangled threads. It leaves these webs at night to hunt.1

Često se miješa s: Other recluse spiders look similar. The violin marking is not a reliable guide, so the eye arrangement is the more important feature for identification. Six eyes in three pairs is the key clue.1

Otrovna snaga

Ugrizi

Otrov izlazi kroz očnjake ili zube kad ugrize.

Što radi njegov otrov kad ugrize ili ubode?

Its venom contains sphingomyelinase D, a substance that destroys skin and tissue. Most bites cause mild irritation, but serious bites can cause a necrotising skin ulcer, which is an open wound where tissue dies. In 10 to 15% of cases, the venom causes a whole-body condition that damages organs, blood cells and kidneys. Bites may feel fine at first, and visible damage can take up to seven hours to appear, while the venom can spread through the body within minutes.1

Koliko je opasno za ljude?

Opasnost za ljude: OzbiljnoUgriz treba pokazati liječniku. Smrtni slučajevi su vrlo rijetki.

Its bite often causes serious reactions, up to and including death. In a study covering 30 years of bites in Chile, 3 to 4% of cases ended in death. In a study of 250 cases in Santiago, Chile, from 1955 to 2000, 9 of the 47 people with the most severe whole-body reaction died. Skin damage can take months, and sometimes years, to heal, leaving deep scars.1

Dobre vijesti: liječnici za ovo imaju lijek (protuotrov) ili liječenje.1

Što radi kad se uplaši?

It is not aggressive and usually bites only when it is pressed against skin, such as when someone puts on clothing where it is hiding.1

Ako ugrize

Applying an ice pack helps, because the venom is more active at high temperatures. Aloe vera may soothe the skin and help control pain.1
Operi ugriz i stavi na njega vrećicu leda protiv boli. Potraži liječničku pomoć ako je bol jaka, širi se ili se osoba osjeća loše.

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

Its venom contains sphingomyelinase D, which is otherwise found only in a few harmful bacteria.1

Its venom contains about ten times more of this substance than other sicariid spiders, such as the brown recluse, according to one study.1

A colony has lived in the Natural History Museum of Helsinki, probably introduced through fruit shipments in the 1960s and 1970s.1

It can survive for a long time without food or water, which helps it spread to new places around the world.1

Chile's Loxosceles laeta can produce 60 μg of venom by electrical stimulation, more than the related Loxosceles intermedia and Loxosceles gaucho.1

Razbijač mitova

Mit: The violin-shaped marking on its back is a reliable way to identify it.

Istina: The marking may not be visible and is not reliable. Counting the eyes, which are six in three pairs, is more important for identification.1
