The Trap Door Spiders are a literary, male-only eating, drinking, and arguing society in New York City, with a membership historically composed of notable science fiction personalities. The name is a reference to the reclusive habits of the trapdoor spider, which when it enters its burrow pulls the hatch shut behind it.[1][2][3]
