A predatory spider waits to ambush an unsuspecting insect on a Queen Anne's lace flower growing in a field near Roseburg, Ore., on Sunday, July 29. The seeds of the plant, also known as wild carrot, were once thought to be a form of birth control. The U.S. Department of Agriculture lists Queen Anne's lace as a noxious weed.

Wild plants covered in spiders' webs in Wagga Wagga on March 7, 2012.
Experts said the spiders may be spinning the sticky webs to help them survive the deluge, which has forced thousands of people to leave their homes over the past week.
"What we've seen here is a type of wolf spider," Owen Seeman, arachnid expert at Queensland Museum, told Reuters. "They are trying to hide away (from the waters)."
The spider webs were seen near the inland city of Wagga Wagga in New South Wales, where 8,000 people were forced from their homes before the flood waters receded on Wednesday.
Thousands of spiders are spinning webs across parts of Australia that are dealing with severe flooding. Msnbc.com's Dara Brown reports.
The Australian Museum's entomology collections manager Graham Milledge said the spiders' behavior was known as ballooning, and was typical after spiders are forced to flee from floods.
"They often do it as a way of dispersing and getting into a new area," Milledge told the news.com.au website. "In an event like this, they are just trying to escape the floods."
Last year PhotoBlog published images of a similar phenomenon in Pakistan.
