What are black widow spiders?

Like all species of spiders, black widow spiders are arachnids. They are a beneficial pest because they feed on and help to control populations of nuisance insects. You can identify a black widow spider by its glossy, black body and legs, and a unique reddish-orange hourglass-like shape on the belly. They also have eight legs, eight eyes arranged in two rows of four, and a comb foot (a row of curved bristles located on the hind pair of legs) that allows them to wrap their prey in silk.

Are black widow spiders dangerous?
