This might not be “Charlotte” writing in the web for Wilbur, but there is a pig nearby and there is some extra markings in the web as the Zipper or Writing spider makes a zigzag pattern in the web. Argiope aurantia is commonly known as the black and yellow garden spider, zipper spider, corn spider, and writing spider. The females are much larger than the males and this female is wrapping up a snack so she had plenty to eat as she makes her egg sac which can contains between 400 and 1400 eggs.
