What Do Black Widow Spiders Look Like? Black widow spiders are famous for their striking hourglass marking, but there's more to them than that. Here's a breakdown of their key features: Color: Black widows are typically shiny black, though some females can be brownish-black. This dark color is a warning sign to predators. Hourglass marking: This is the most recognizable feature! It's a bright red hourglass on the underside of the female's abdomen. Sometimes, it may appear as two separate red triangles instead of a complete hourglass. Size: Black widow females are larger than the males. Their bodies are usually between 3 to 10 mm (around 1/8 to 3/8 inch) in size. The males are even smaller, at about one-fourth to one-half the size of the females. Other features: Black widows have eight legs and eight simple eyes. They also have a special row of curved bristles on their hind legs called a "comb foot," which they use to spin silk and wrap up their prey.
