Fairly certain this is an American Nursery Web Spider (Pisaurina mira). This was one that caught me super off guard while rummaging through a portion of priory while leading a Tiny Nature hike with @hikehoppers. P. mira is most well known for its sexually cannibalistic behavior and extensive use of the silk web in mating. Before mating, the male binds the female’s legs with his silk so she can’t eat him. The nursery part of the name though comes from the structure in which the egg sac is hung.
