The bolas spider can attract male moths by mimicking the scent of a female. It uses a blob of glue dangling by a thread to catch them when they come close. The spiders bolas is named after an old hunting weapon still used in South America. Gauchos throw these weighted ropes around the legs of cattle to bring them down. The spider's version is sticky and is cued by the beating of wings. The thread is stronger than steel and few moths escape.
