A TRAPDOOR SPIDER COLONY WELL CAMOUFLAGED The female spider deftly covers the top of her trapdoor with earth similar to the surrounding surface, to hide it from the view of unsuspecting sow bugs, grasshoppers, and other favorite insects. If the nest is located in mossy soil, the spider will stick the roots of living moss into the door as expertly as a true gardener. The nests vary in depth from two to nine inches, depending upon the age of the spider. Photographs ©Lee Passmore THESE TRAPDOORS WERE OPENED BY HAND Female spiders living asclose together asthis seldom see their next-door neighbors (see illustrationopposite). They never voluntarily come out of their nests and crawl around the ground. When feeding at night, the door is open only for a fraction of asecond while the spider makes acapture, but always part of the body iskept inthe opening ofthe nest toprevent the trapdoor from snapping shut (see text, page 195).
