Garden Spiders are big and beautiful, they are one of my favorite arachnids! Their bright yellow and black markings are warning signals to birds not to eat them. The zigzag lines on the web may be an attractant for insects or they may be to help repel birds. I've had students tell me, "If a Writin' Spider writes your name in its web, you'll die!" My response is a smile and I say, "Well, unless your name is 'ZZZZZZZ', you don't have to worry about it!"
