Introduction (Back to Top)
Most commonly known as the yellow garden spider, Argiope aurantia Lucas is a large orb-weaving spider. Argiope aurantia is also known as the writing spider due to the trademark vertical zig-zag pattern they construct in their webs (Enders 1973).
Distribution (Back to Top)
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).
Description (Back to Top)
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.
Web Building Behavior (Back to Top)
Initially, webs tend to be placed in areas sheltered from wind and are around 15 cm from the ground. As spiders age, the preference for higher web placement increases (Enders 1977). Starting with males of the sixth instar and females of the twelfth instar, there is no longer a noticeable preference to shield the webs from winds (Enders 1977).
Hosts (Back to Top)
The yellow garden spider has been observed catching and feeding primarily on the orders Odonata (dragonflies and damselflies) and Hymenoptera (wasps and bees).
Enemies (Back to Top)
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).

Life History/Behavior
- In early spring, the spiderlings, numbering from 500 to 1,000, emerge from the egg sac. Many of them will succumb to cannibalism and predation from mud-dauber wasps. Those that do survive are usually unnoticed by humans until they reach maturity in the late summer.
Medical Importance
- Although these large, showy spiders sometimes cause alarm to individuals who are uncomfortable with spiders, they are not known to be medically important. People are not likely to be bitten unless they handle a female with an egg sac in the web. Even then, the bite would likely cause no more discomfort than a wasp or bee sting for most individuals.
