Loxosceles deserta, commonly known as the desert recluse, is a brown spider of the family Sicariidae.[1]
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.[2]
Distribution
This spider is found in the eastern half of southern California, the southern tip of Nevada, the western half of Arizona, the southwestern corner of Utah,[3][4] and into Mexico.[5]
It dwells in the wild, and its only domestic occurrence is that near native vegetation, avoiding urban areas in the desert and even green lawns.[2] The spiders are particularly dense in packrat dens.[6]
Venom
Lesions of the skin can be caused by the venomous bite of the desert recluse.[7] This occurs through the same mechanism responsible for the effects of the brown recluse bite.[citation needed]
