Silver Garden orb weavers are common in the south in states such as Texas, Arizona, and Florida. These types of Spiders in Louisiana might be found outdoors under piles of wood or rocks or inside crevices. [19] While early molecular analysis provided more support for a monophyletic origin,[10][13][14] other evidence indicates that orb-weavers evolved earlier phylogenetically than previously thought, and were extinct at least three times during the Cretaceous. These decorations have an unproven role or benefit as nobody knows why spiders prefer to decorate their webs by this method. Many of the studies on this spider have taken place in citrus groves in Florida. While mildly painful, their bite poses no threat to humans.
