A TRAPDOOR SPIDER LINES A JAR WITH A FILMY. WEB Placed in the jar on a dark shelf and forgotten, this lady spider tried to make a nest out of her temporary home. When found, the jar looked as if it contained milk, for web lining covered the walls but not the top. Photographs ©Lee Passmore NOT TWO SPIDERS-BUT ONE AND ADISCARDED SKIN This spider, having shed only two days before, was too weak tomove, and had to be lifted intothe position shown inthe photograph. Trapdoor spiders (see page 210) begin toshed when they are about two months old.
