Spider bites often turn dark due to necrosis, which is the death of skin tissue around the bite area. Additionally, bites from certain types of spiders like the brown recluse can cause a darkening of the skin as the body responds to the venom. It's important to monitor the bite for signs of infection or an allergic reaction and seek medical attention if the area becomes increasingly painful, swells, or shows signs of infection.
