The average size of mature Chilean Recluse spiders is approximately 5/8 of an inch, with a leg span of 1.5 to 2 inches. Male and female are similar in size. The Chilean Recluse is one of the largest recluse spiders.


Chilean Recluse spiders are generally yellowish-brown to reddish-brown in color, with a darker colored violin shaped marking on the top of the cephalothorax (not the abdomen). The violin is easy to see in the photos on this page. The abdomen is a uniform color, with no markings on it.

Chilean Recluse spiders, and the other related recluse spiders, have six eyes arranged in three pairs of two. This is a rather unique feature, as most spiders have eight eyes. A magnified view of the eyes can be seen in a photo below.


The Chilean Recluse is an introduced species that is found in California. The Chilean Recluse has also been reported in the past as living in the basement of the Museum of Comparative Zoology at Harvard University in Massachusetts. Outside of the United States, the Chilean Recluse is found in South America where it is native to Argentina, Brazil, Chile, Ecuador, Peru, and Uruguay. It has also been introduced into Australia, Finland, and Guatemala.

The Chilean Recluse is known to have a necrotic bite. This means that the bite causes severe damage to the skin and surrounding tissue, resulting in a large open sore, called a necrotic lesion, that takes a long time to heal. In some cases, systemic effects (i.e. headache, nausea, abdominal cramps, joint stiffness, and/or fever) have been reported as well. Of all the recluse spiders, the Chilean Recluse reportedly has one of the most venomous bites.

Often the Recluse spiders are called Violin Spiders or Fiddleback Spiders, because of the characteristic violin marking. They are also called Brown Spiders in some areas.

Below is a photo of a Brown Recluse, which is similar in appearance to the Chilean Recluse. Note the violin marking that is found on many recluse spiders, including the Chilean Recluse.
