what kind of spider has a bright yellow back
Argiope aurantia The spider species Argiope aurantia is commonly known as the yellow garden spider,[1][2] black and yellow garden spider,[3] golden garden spider,[4] writing spider, corn spider, or McKinley spider.[5] 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 genus name Argiope meaning "silver-face", while the specific epithet aurantia means "gilded"). Males range from 5–9 mm (0.20–0.35 in); females range from 19–28 mm (0.75–1.10 in). These spiders may bite if disturbed or harassed, but the venom is seemingly harmless to humans.[6]
Latrodectus Widow spiders can be found on every continent of the world except Antarctica. In North America, the black widows commonly known as southern (Latrodectus mactans), western (Latrodectus hesperus), and northern (Latrodectus variolus) can be found in the United States, as well as parts of southern Canada â€“ particularly in the Okanagan Valley of British Columbia, as can the "gray" or "brown widow spiders" (Latrodectus geometricus) and the "red widow spiders" (Latrodectus bishopi).[16] The blue mud dauber (Chalybion californicum) is a wasp that is the primary predator of black widow spiders.[17]
