Comments
========
Argiope aurantia, 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, is a species of spider found in the contiguous United States, Hawaii, southern Canada, Mexico, and Central America. Its distinctive features include yellow and black markings on the abdomen and a mostly white cephalothorax. The scientific Latin name translates to “gilded silver-face,” with the genus name Argiope meaning “silver-face” and the specific epithet aurantia meaning “gilded”. These spiders are large, orb-weaving arachnids that spin circular webs. These spiders are diurnal carnivores and may bite if disturbed, but their venom is harmless to non-allergic humans, roughly equivalent to a bumblebee sting in intensity.
