SPIDERS are known for many things. Sociability is not one of them. Most spiders are more likely to try to eat their neighbours than befriend them. Given that there are at least 43,678 species of the critters, though, it is not too surprising that a few have overcome their natural grumpiness and teamed up to form societies. So far, about two dozen such social spiders have been identified. And among them, something really strange has just been found.
