According to a recent Seattle Times article, many of the spiders we see are European cross spiders. In my yard they seem to like to start at my mailbox and then migrate to different areas.
They mostly hide in bushes until they are big. Then they build very large webs and are able to eat many insects including bees.
Mailbox pictures were taken with the a macro lens and the camera's build in flash.
We caught this one enjoying a bee. The web is between our sunflower and tomato plants, and is between two and three feet in size.
