How can you identify a Black Widow spider?

The identification of a Black Widow spider is primarily based on its distinctive appearance. The correct choice describes a female Black Widow spider, which is known for its shiny black body and the characteristic red hourglass marking located on the underside of its abdomen. This striking coloration serves as a warning to potential predators of its venomous nature.

Recognizing these features is crucial for safely identifying the species, as the female is the most recognizable and dangerous member of the family. In contrast, the male Black Widow is smaller, less harmful, and often does not have the same noticeable hourglass marking.

The other options present characteristics that do not align with the common description of the Black Widow. For example, a brown spider with a black stripe, or one described as large and hairy, does not match the typical appearance of a Black Widow, further emphasizing the uniqueness of the female's coloration and markings.
