Spiders' nesting sites may vary depending on species-specific requirements and environmental conditions. I report on the use of leaves of Sarracenia purpurea (Purple Pitcher Plant) as oviposition sites by 5 species of spiders in Virginia and North Carolina. The presence of egg sacs, webbing, and a protective female spider inside the pitchers confirmed the spiders' use of the carnivorous plant trap as a safe and secure nest rather than a deadly mechanism by which many spiders have commonly become victims. I also collected spiders in the surrounding environment to determine if this microhabitat is used by uncommon species or ones that are often found nearby. Almost all spiders found within pitchers of S. purpurea were also found in the surrounding environment, but not at high densities near S. purpurea. The decaying pitchers of S. purpurea may create an ideal home for many spider species in environments where suitable oviposition sites are hard to come by.
