Miami, with its tropical allure, is not just a hotspot for tourists but also for a diverse range of wildlife. Among its residents is the Northern Black Widow Spider, Latrodectus variolus, a creature both fascinating and feared.
While the Northern Black Widow is more commonly associated with regions further north, it has made its presence felt in South Florida. Its distinctive markings and potent venom have made it a subject of both intrigue and caution.
Female Northern Black Widows typically measure between 1 to 1.5 inches when including their leg span. Males, on the other hand, are considerably smaller, often half the size of females.
Originally native to the northern regions of the United States, this spider has expanded its range, with sightings reported in Miami. Its adaptability has allowed it to thrive in various environments.
Preferring dark, secluded spots, the Northern Black Widow often takes refuge in woodpiles, sheds, or basements. The warm and humid climate of South Florida provides ample prey and suitable nesting spots.
