Argiope aurantia
Orb Weavers
The subject is identified as Argiope aurantia based on the combination of its large size, distinctive yellow and black patterned abdomen, banded legs, and the presence of a prominent vertical zigzag stabilimentum in its orb-web. These features are all characteristic and diagnostic for a female of this species, commonly known as the Yellow Garden Spider, and clearly distinguish it from other large orb-weavers in the region.
Field notes
Observation of a female Yellow Garden Spider (Argiope aurantia) in Flatonia, TX, in August. Noted for its distinctive yellow and black patterned abdomen, banded legs, and a prominent vertical zigzag stabilimentum in its orb-web. These spiders are generally not aggressive and their venom is harmless to non-allergic humans, comparable to a bumblebee sting. The zigzag stabilimentum is a dense, silken structure woven into the web, appearing as a vertical, zigzagging band of non-capture silk.
Overview
Conservation
Not evaluated
Argiope aurantia is a species of spider, 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. The species was first described by Hippolyte Lucas in 1833. It is common to the contiguous United States, Hawaii, southern Canada, Mexico, and Central America. It has distinctive yellow and black markings on the abdomen and a mostly white cephalothorax. Its scientific Latin name translates to "gilded silver-face". The body length of males range from 5–9 mm (0.20–0.35 in); females range from 19–28 mm (0.75–1.10 in). The average female body mass is about 752.0 mg. These spiders may bite if disturbed or harassed, but the venom is harmless to non-allergic humans, roughly equivalent to a bumblebee sting in intensity.
