This very common spider is identifiable by its cobweb-like homes. This particular species can be found throughout the southern United States, including Louisiana. They can move along the waters surface before diving below, using air bubbles to breathe under water. As orb-weavers age, they tend to have less production of their silk; many adult orb-weavers can then depend on their coloration to attract more of their prey. When threatened, they will move quickly to escape predators or potential threats to their safety. It primarily feeds on ants. A distinct trait of the Banded Garden spider web is that its also characterized by various decorations known as stabilimenta. Many males die afterward by being eaten by the female.
