Black and Yellow Garden Spiders

Black and yellow garden spiders (Argiope aurantia) measure approximately 3 cm in body length and are easily identified by the presence of silver hairs on the anterior of their bodies. Their abdomens are also marked vividly in black and yellow.

Black and yellow garden spiders hang upside down from the center of their webs while waiting for prey to approach. Webs are attached to branches, bushes and tall grass in order to remain stable. Black and yellow garden spiders weave their webs in open, visible locations, allowing for easy capture of flying prey.

While generally considered harmless to humans, the black and yellow garden spider can bite when provoked. Its venom, however, has not been known to cause any serious medical reactions in humans.
