Spiders making spiders AARON COHEN · DEC 26 2012
Scientists in Peru have discovered what they think may be a new species of spider which uses twigs and dead insects to build decoy spiders to trick predators.
Afterward, Torres returned to the trails near the research center. Only within a roughly 1-square-mile area near the floodplain did Torres find more spider-building spiders -- about 25 of them. "They could be quite locally restricted," he said. "But for all I know, there's millions of them in the forest beyond." The spiders' webs were crafted around face-height, near the trail, and about the width of a stretched-out hand. Some of the decoys placed in the webs looked rather realistic. Others resembled something more like a cartoon octopus.
