Loxosceles deserta, commonly known as the desert recluse, is a recluse spider of the family Sicariidae. [1] It is found in Mexico and the United States. The desert recluse is commonly misidentified as L. unicolor (of South America) [2] or as L. reclusa (the brown recluse of the southern and midwestern states), two spiders which do not live anywhere near the vicinity.
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 desert recluse is one of the two most common types of recluse spiders in Arizona. It is often mislabeled as a brown recluse in Western Arizona, Southern California and the southern tip of Nevada.
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 ...
These spiders are brown in color with long legs attached to a body of roughly 9 millimeters in length, Penn State Extension writes. Brown recluse spiders sport three pairs of eyes arranged in a ...
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.
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 ...
