What is the common name for Loxosceles reclusa?

The correct answer, Brown recluse, refers to Loxosceles reclusa, which is a significant species of venomous spider primarily found in the United States. This spider is characterized by its distinctive violin-shaped mark on its back, which aids in its identification. The brown recluse is notable for its necrotic venom, which can cause serious skin lesions in humans.

The name "Brown recluse" reflects both the spider's coloration and its tendency to hide in secluded, dark areas, such as woodpiles, closets, and other undisturbed spaces. Understanding the common names and scientific nomenclature of species is critical in medical and emergency situations, especially when it comes to diagnosing bites or treating patients effectively.

This knowledge assists healthcare professionals in providing appropriate care for spider bites, as the brown recluse's bite can lead to significant medical complications. The other names listed—Black widow, Banana spider, and Redback spider—refer to different species that, while also relevant in the context of venomous spiders, do not apply to Loxosceles reclusa specifically.
