This garden spider (Argiope aurantia), and her future offspring live on our front porch. Each year - we let the spiders go ahead and multiply as they are a truly beneficial visitor. A bit startling to come upon, but when nesting - they usually pic a corner of a door or window sill to set the nest. This nest sac is one of the largest we have seen in years. Wet weather this summer and the increase in small insects may be the reason. Hope you enjoy!
