Large Black & Yellow Garden Spider (Argiope aurantia)



Photo taken in Montgomery County near Porter, Texas. The Black and Yellow Argiope is a common orb web spider. Orb web means it spins a web like a circle.
Female spiders are much larger than males, growing almost an inch and a half long. Males grow about 3/4 inch long. Both spiders have a cephalothoraxes (small front body section) with silver hairs on it. The abdomen (large back section) is egg-shaped with black and yellow coloring.
Legs of these spiders are black with red or yellow bands. Each leg has three claws on the end.
Black and Yellow Argiopes live in fields and gardens. They can be found on shrubs, tall plants, and flowers.
The web of this spider spirals out from the center and can be two feet across. The female builds the large web, and a male will build a smaller web on the outer part of her web. The male's web is a thick zig-zag of white silk.
