The Chilean recluse spider, Loxosceles laeta, is a highly venomous spider of the family Sicariidae. In Spanish, it (and other South American recluse spiders) is known as araña de rincón, or "corner spider"; in Brazilian Portuguese, as aranha-marrom or "brown spider". It is considered by many to be the most dangerous of recluse spiders, and ...
Similar to those of other recluse spiders, their bites sometimes require medical attention. The brown recluse is one of three spiders in North America with dangerous venom, the others being the black widow and the Chilean recluse. Brown recluse spiders are usually between 6 and 20 millimetres (0.24 and 0.79 in), but may grow larger.
The Chilean recluse (L. laeta) supposedly has a more potent venom, which results in systemic involvement more often. All Loxosceles species that have been tested have venoms similar to that of the brown recluse, and all should be avoided. In general, though, they are not aggressive and commonly occupy human dwellings without causing problems.
The brown recluse typically lives up to its name: The spider is quiet, shy, and really just wants to be left alone. Nonetheless, it gets blamed for thousands of gruesome bites each year. That’s ...
As well as the Chilean recluse spider, the venom of Loxosceles intermedia has a high concentration of the enzyme sphingomyelinase D. [5] responsible for local and systemic effects, and is one of the main species attributed to deaths in South America, since the systemic effects of the bite occur frequently. The symptoms are not immediate, which ...
There have been documented cases of homes having very large populations of brown recluse spiders for many years without any of the human inhabitants being bitten. For this reason, L. reclusa bites are relatively rare, but, because its range overlaps human habitation, its bite is the cause of loxoscelism in North America.
