Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Latrodectus hesperus, the Western black widow spider or Western widow, is a venomous spider species found in western regions of North America. The female's body is 14-16 millimeters in length and is black, often with an hourglass shaped red mark on the lower abdomen. This "hourglass" mark can be yellow, and on rare occasions, white. The male of the species is around half this size and generally a tan color with lighter striping on the abdomen. The population was previously described as a subspecies of Latrodectus mactans and it is closely related to the northern species Latrodectus variolus. The species, as with others of the genus, build irregular webs.
