A. Feeding Habits

B. Black Widow Spider Habitats

The black widow spider is found in many different habitats throughout the world. In North America, they are commonly found in the southern and western United States. They can also be found in parts of Canada, Mexico, and Central America.

Although black widows are known to be aggressive against other spiders, they are also typically shy and reclusive.

When it comes to mating, the males take a more active role. Males will often travel long distances to find a mate.

Once they find a female, they will spin a web around her and begin to court her. If she is receptive, the two will mate.

After mating, the female will lay eggs (up to 750 eggs per summer) which she will then guard fiercely. The young spiders will stay with their mother for a few weeks before going off on their own.

D. Black Widow Spider Social Behavior

Although black widow spiders are solitary creatures, except when mating, it is not uncommon for them to be found in large groups, often sharing web space with other spiders.
