What is that black and yellow spider in my garden?
A. If you are in America it is the Black and Yellow Argiope, Argiope Aurentia, a very common and harmless garden spider. In Australia, they are known as St Andrew Cross spiders, Argiope mangal, because of the white markings in their web which resemble St Andrew’s cross. Other types of Argiope include the Banded Argiope and the beautiful Silver Argiope. Unfortunately this lovely spider only has a short life span and once she has produced one or more (usually no more than 3) brown, papery egg sacs, she will die.
