The Golden Orb Weaver Spider can be a very scary looking web and with a big spider in them. They actually are a beneficial spider because the eat other spiders.
They often are referred to simply as Garden Spiders
Orb weavers are a "lay-in-wait" predator, preferring to let the food come to them. Their webs are built in conspicuous locations, often across gaps that might serve as flight paths for insects such as moths or flies, and the sticky strands of the orb weaver's web do a marvelous job of capturing these other bugs.
