I had a cellar spider in my bathroom, about a foot to the left and a foot above my sink since last September. I enjoyed seeing the spider every morning as I shaved. The spider had a well-stocked web with a fly and many mites. The spider was in the regular spot in the web when I left Friday morning, nobody else was in the house in the interim, the door was shut and when I came home the spider was gone! No body, no sign of the spider. I checked the sink and the bathtub. I obviously didn't do a complete search of the house, like looking under heavy furniture, but cellar is no where to be seen on any of the ceilings. Any ideas? Is this unusual for them to wander after such a time? I've seen them before, of course, but never took long term notice of them. Thanks for any ideas.
