The Argiope Aurantia or black and yellow garden spider appears in every US state and in many other countries around the world. It is characterized by its black and yellow abdomen and a beautifully patterned web. Argiopes are Orb Weavers, but due to their differences from other Orb Weavers, they are often put into their own group.
Argiope Spider Description
The Black & Yellow Argiope is very easy to identify, as it looks completely different from any other spider. The cephalothorax always has a light gray, white or silvery shade to it. The abdomen is nearly twice the size and very oblong, with a wide black area running down the center and the sides covered with yellow patches. The long, thinner legs will be orange (Dark Yellow) close to the body with black becoming more prominent out towards the ends. Apart from its colors, it is very similar to the Argiope trifasciata or banded garden spider and the silver garden spider (Argiope argentata).
Argiope Aurantia Quick Facts
Abdomen – Large (more than double the cephalothorax) and oblong shaped. Usually black with white and yellow patterns.
Cephalothorax – White (or light Gray) and slightly dull and fuzzy looking.
Female Size – The body of the female Argiope can grow to be a little larger than one inch (25 mm). Including the legs, they can grow to over three inches, making them one of the largest spiders in Michigan.
Male Size – Much smaller than the female. Male Yellow Garden spiders are typically only 1/4 inches.
Argiope Aurantia Web
Like other Orb Weavers, the Argiopes spin large round webs for catching flying insects. However, the one way you can tell an Argiope’s web from any other is the thick zigzag pattern towards the center of the web. It is believed that is special decoration of the web should make the spider appear larger and more dangerous to predators.
Argiope Spider Bite
The Argiope bite is not dangerous to humans. The worst bites will cause some mild localized pain, itchiness, and swelling that will fade in a few days. Most bites will not even be that bad.
