The yellow garden spider is a common species that frequently captures ...

What are yellow spider eggs?

Eggs: Yellow garden spider eggs are spherical and range in color from white to light brown. Eggs are placed in white multilayered tear drop shaped egg sacs, suspended within the spider’s web. These egg sacs are made of a flocculent (wool like) layer of silk used to buffer the eggs and spiderlings from any potential short-term fluctuations of temperature ( Figure 2 ). This flocculent layer is located between the spiderlings and the shell, or outer layer, of the egg sac (Hieber 1985). The yellow garden spider preferentially attaches egg sacs to webbing underneath vegetation or under the coverage of broad-leaved plants (Hieber 1985).

How does Argiope aurantia wrap its prey?

Alternatively, Argiope aurantia may wrap the prey in another technique called rotational swathing, where the prey is wrapped by the spider rotating and attaching silk to the prey simultaneously (Harwood 1974).

What spiders attack Argiope aurantia?

Smaller, younger Argiope aurantia are susceptible to attacks from salticid spiders, commonly known as jumping spiders (Tolbert 1975). Due to their large size, adult Argiope aurantia attacks by salticid spiders are often deterred and salticids may even be preyed upon if caught in the web (Tolbert 1975). Mud daubers will commonly prey on Argiope aurantia. In response to their own predators, Argiope aurantia will create up to two barrier webs within their primary orb web. Barrier webs serve as a physical barrier to some predators by preventing easy access onto the web. Barrier webs are placed on the exterior edges of the orb and more importantly serve to alert the spider of any disturbances in the web (Tolbert 1975).

How do juvenile Argiope aurantia disperse?

Like many spiders, juvenile Argiope aurantia disperse by catching wind currents on silk they release, commonly known as ballooning. Younger spiders typically balloon vertically and begin to balloon horizontally as they mature due to their increased size. Adults are too large to balloon. Figure 3.

Where do Argiope aurantia live?

Argiope aurantia resides in Central and North America and is most common in the eastern portion of its range (Levi 1968). They occur in a variety of habitats such as along edges of water bodies, grassy hillsides (Levi 1968), and woodlands (Fitch 1963). The highest densities of Argiope aurantia occur at edge habitats, or where two different habitats meet (Enders 1973). The yellow garden spider frequently is observed in areas disturbed by human development, such as roadsides, farms, and gardens (Enders 1973).

What does it mean when a spider is at rest?

Spiders seen at rest on the hub or center of the web are feeling for vibrations from intruders or prey (Harwood 1974).

What is a spider web?

The web consists of dry spokes supporting a spiral thread of adhesive silk. The hub is separated from the spirals by a free zone. The spiders rest head down day and night at the hub of the web over a conspicuous zigzag band of bright white noncapture silk known as a stabilimentum. The stabilimentum apparently affords protection, perhaps by camouflaging the spiders, startling predators, or acting as an aposematic warning of the presence of webs. It seems to be especially effective in preventing birds from flying through webs. However, it can also cost spiders the loss of prey, and hungry spiders, which most need to capture prey, are less likely to build stabilimenta (Blackledge 1998; Blackledge and Wenzel 1999). The female usually eats her web each day and constructs a new one, often in the same place (Reed et al. 1969). Females can handle prey much larger than themselves, including grasshoppers, katydids, cicadas, June beetles, moths, wasps, bees, and other insects (Fitch 1963). In east Texas cotton fields, major prey items are aphids, flies, grasshoppers, and ants and bees (Nyffeler et al. 1987).

Do spiderlings disperse in spring?

Spiderlings winter over inside the sacs, and they disperse in the spring. Mortality due to predators and parasites can be very high (Lockley and Young 1993). In the spring, the young spiders build small webs in low vegetation. As they grow, they tend to build larger and more conspicuous webs higher in vegetation.

Overview

The spider species Argiope aurantia is commonly known as the yellow garden spider, black and yellow garden spider, golden garden spider, writing spider, zigzag spider, zipper spider, black and yellow argiope, corn spider, Steeler spider, or McKinley spider.

Habitat

Yellow 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.
Female Argiope aurantia spiders tend to be somewhat local, often staying in one place throughout much of their lifetime.

Distribution

This spider is found from Canada to Costa Rica, but less so in the basin and mountain areas of the Rockies.

Venom

Argiope spiders are not aggressive. They might bite if grabbed, but other than for defense they do not attack large animals. Their venom often contains a library of polyamine toxins with potential as therapeutic medicinal agents. Notable among these is the argiotoxin ArgTX-636.
A bite by Argiope aurantia is comparable to a bee sting with redness and swelling. For a healthy adult, a bite is not considered an issue. Though they are not aggressive spiders, the very young, elderly, and those with compromis…

Reproduction

Yellow garden spiders breed twice 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. The male uses the palpal bulbs on his pedipalps to transfer sperm to the female. After inserting the second palpal bulb, the male dies, and is sometimes then eaten by the female.

Eating habits

Females of the species are the most commonly seen in gardens. Their webs are usually characterized by a zigzag shaped stabilimentum (an extra thick line of silk) in the middle extending vertically. The spiders spend most of their time in their webs, waiting for prey to become ensnared. When prey becomes caught in the web, the spider may undulate the web back and forth to further trap the insect. When the prey is secure, the spider kills it by injecting its venom and then wraps the prey in a cocoon of silk for later consumption (typically 1–4 hours later). Prey incl…
