Yellow Garden Spider

Argiope aurantia

The spider species ''Argiope aurantia'' is commonly known as the yellow garden spider, black and yellow garden spider, golden garden spider, writing spider, or corn spider. It is common to the contiguous United States, Hawaii, southern Canada, Mexico, and Central America. They have distinctive yellow and black markings on their abdomens and a mostly white cephalothorax.
Yellow Garden Spider (Argiope aurantia) I thought our new "family member" on the front porch had surely reached her expiration as she disappeared yesterday morning without a trace. However, I woke up to the sight of this today! Congratulations to the new Mama! :D

Males range from 5–9 mm, females from 19–28 mm. These spiders may bite if disturbed or harassed, but the venom is seemingly harmless to humans.
Zipper Spider - Argiope aurantia Total length (with legs): 40-45 mm.  

I watched this beautiful, black and yellow spider wrap up a snack in her web this morning.  The web had a stabilimentum (reinforced area), which looks like a vertical zigzag band near the middle of the web.

Habitat: Suspended between plants on the edge of a pond in a mixed forest.

The etymology of its name means "gilded silver-face".
In the pink A beautiful Argiope aurantia female that had made her home in the garden of the property where I was staying....she really was 'in the pink' in regard being a healthy specimen, but also the house wall behind provided a very pretty pink backdrop for some photographs. 
Focus on her beautiful abdomen, but a little detail lost on the legs due to deep depth of field.

The web of the yellow garden spider is distinctive: a circular shape up to 2 feet in diameter, with a dense zigzag of silk, known as a stabilimentum, in the center. The purpose of the stabilimentum is disputed. It is possible that it acts as camouflage for the spider lurking in the web's center, but it may also attract insect prey, or even warn birds of the presence of the otherwise difficult-to-see web. Only those spiders that are active during the day construct stabilimenta in their webs.

The garden spider can oscillate her web vigorously while she remains firmly attached in the center. This action might prevent predators like wasps and birds from drawing a good bead, and also to fully entangle an insect before it cuts itself loose.

In a nightly ritual, the spider consumes the circular interior part of the web and then rebuilds it each morning with fresh new silk. The radial framework and anchoring lines are not usually replaced when the spider rebuilds the web. The spider may be recycling the chemicals used in web building. Additionally, the fine threads that she consumes appear to have tiny particles of what may be minuscule insects and organic matter that may contain nutrition.

The garden spider does not live in very dense location clusters like other orb spiders such as the golden orb web spider. The garden spider keeps a clean orderly web in comparison to the cluttered series of webs built and abandoned by groups of golden orb spiders.

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.

Yellow garden spiders breed once a year. The males roam in search of a female, building a small web near or actually in the female's web, then court the females by plucking strands on her web. Often, when the male approaches the female, he has a safety drop line ready, in case she attacks him. After mating, the male dies, and is sometimes then eaten by the female.

She lays her eggs at night on a sheet of silky material, then covers them with another layer of silk, then a protective brownish silk. She then uses her legs to form the sheet into a ball with an upturned neck. Egg sacs range from 5/8" to 1" in diameter. She often suspends the egg sac right on her web, near the center where she spends most of her time. Each spider produces from one to four sacs with perhaps over a thousand eggs inside each. She guards the eggs against predation as long as she is able. However, as the weather cools, she becomes more frail, and dies around the time of the first hard frost.

In the spring, the young spiders exit the sac and are so tiny that their collection of bodies look like dust gathered inside the silk mesh. Some of the spiderlings remain nearby, but others exude a strand of silk that gets caught by the breeze, carrying the spiderling to a more distant area.
