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

Native to South America, including Chile, Peru, Ecuador, Argentina, Uruguay and southern and eastern Brazil1

Hasiera

Dry, undisturbed places such as woodpiles, sheds, closets and garages. It is often found in human homes. It has also been found in buildings in the USA, Canada, Australia, Sweden, Finland and Germany, although it does not thrive in most of these places.1

Nola ezagutu

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

Askotan honekin nahasten da: 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

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zer egiten du bere pozoiak?

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

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

Albiste ona: medikuek badute sendagai bat (antipozoia) edo tratamendu bat honetarako.1

Zer egiten du beldurtzen denean?

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

Kosk egiten badu

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

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.

jakin beharrekoa

Datuak

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

Mito-hauslea

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

Egia: 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
