Chilean Recluse

Loxosceles laeta

Not Evaluated

It has not yet been assessed against the IUCN criteria. See full glossary

The Chilean recluse, also called the violin spider, and in Spanish reclusa chilena, loxósceles argentina, araña de rincón or araña de los rincones, is an araneomorph spider of the family Sicariidae that tends to hide in cracks and hard-to-reach corners, hence its Spanish name. It is regarded as the most dangerous of the spiders of the genus Loxosceles, since its bite frequently causes severe systemic reactions and even death. The arachnid Sicarius is related to this spider and is therefore also considered dangerous.

Fun facts

  • GeneralIts bite can cause the skin to necrose; it is the most dangerous of the recluse spiders.
  • It has six eyes in three pairs rather than eight, a feature it shares with the other recluse spiders.
  • It can survive for months without food or water, which lets it persist in corners of a house that nobody disturbs for long stretches.
  • Most bites happen while dressing or going to bed, when the spider is trapped against the skin; shaking out clothes and moving the bed away from the wall are the most effective precautions.
  • This is the spider known in Spanish as the araña de rincón, and unlike its North American relative, here the problem is real and serious: it causes most of the world's serious cases of loxoscelism.
  • The systemic syndrome, called cutaneous-visceral loxoscelism, includes haemolysis, kidney failure and coagulopathy, and can be fatal, above all in children. It occurs in a minority of cases, but that minority is the one that matters.
  • In Chile it is a recognised public health problem, with public prevention campaigns and antivenom available.
  • It lives inside houses and is extraordinarily synanthropic: most homes in some Chilean cities are estimated to harbour specimens.
  • Like all Loxosceles, it has six eyes in three pairs, and that is the reliable identification character.
  • Most bites happen at night, in bed, or when dressing in clothes that have been put away.
