European garden spider (Araneus diadematus)
The European garden spider, diadem spider, cross spider, or cross orbweaver (Araneus diadematus) is a very common and well-known orb-weaver spider in Europe and parts of North America, in a range extending from New England and the Southeast to California and the northwestern United States and adjacent parts of southern Canada. Individual spiders' colouring can range from extremely light yellow to very dark grey, but all European garden spiders have mottled markings across the back, with five or more large, white dots forming a cross. The white dots result from cells filled with guanine, which is a byproduct of protein metabolism. Adult females range in length from to 20 mm ( to in), while males range from to 13 mm ( to in). The third pair of legs of garden spiders are specialized for assisting in the spinning of orb webs. These spiders also use them to move around on their web without getting stuck. These legs are useful only in the web; while on the ground, these legs are of little value. Since this tends to be a passive animal, it is difficult to provoke to bite—but if it does, the bite is just slightly unpleasant and completely harmless to humans.
