black and yellow garden spider/writing spider/corn spider

Description:

They have distinctive yellow and black markings on their abdomens and a mostly white cephalothorax. Males range from 5–9 mm (0.20–0.35 in) females from 19–28 mm (0.75–1.1 in). Like other members of Argiope they are considered harmless to humans.

Habitat:

Garden spiders often build webs in areas adjacent to open sunny fields where they stay concealed and protected from the wind. The spider can also be found along the eaves of houses and outbuildings or in any tall vegetation where they can securely stretch a web. The circular part of the female's web may reach two feet in diameter. Webs are built at elevations from two to eight feet off the ground. Female Argiope aurantia spiders tend to be somewhat local, often staying in one place throughout much of their lifetime.
