Welcome to a page talking about the Black Widow spider, otherwise known as
the Latrodectus. There are many different species of Latrodectus and often
they are feared by the public due to their known venemous quality and
apparent abundency in the Northern California area. We here in North America
have a wide variety of genus like the red widow and the brown widow.
This is the underbelly of a female black widow spider.
"Female widow spiders are typically dark brown or a shiny black in colour when they are full grown, usually exhibiting a red or orange hourglass on the ventral surface (underside) of the abdomen; some may have a pair of red spots or have no marking at all. The male widow spiders often exhibit various red or red and white markings on the dorsal surface (upper side) of the abdomen, ranging from a single stripe to bars or spots, and juveniles are often similar to the male pattern. Females of a few species are paler brown and some have no bright markings. The bodies of black widow spiders range from 3–10 mm (0.12–0.39 in) in size; some females can measure 13 mm (0.51 in) in their body length (not including legs).[8] Including legs, female adult black widows generally measure 25–38 mm (1–1.5 in)"
