Western Black Widow Spider: Identification, Habitat & Safety #1665684 (License: Personal Use)

This close-up shows a mature female Western Black Widow (Latrodectus hesperus), identifiable by her uniformly glossy black coloration and robust, rounded abdomen; unlike the more famous Southern Black Widow, she typically lacks a red hourglass marking or has a faint one. She is positioned on coarse concrete, surrounded by sparse dry grass, suggesting a peri-urban or sheltered outdoor habitat such as garages, woodpiles, or foundations. Her long, spindly legs are extended, showcasing the species’ characteristic posture when at rest.
