Mud Wasps
Things occur when basic housekeeping falls too far behind.
Back in November I blogged mentioning how one room had been ignored for too long. Since then, little has happened. I entered yesterday wiping away the numerous spider webs in my way, and began by finding a place for some of the things that were simply in the way. I turned to see a surprise stuck to the top of the door.

It measured a couple inches across. I believe it was a nest for some kind of mud wasp. I did not know if it was live or not, but did not want to have this inside the room. I grabbed a board trying to scrape it off. It seemed as hard as concrete. Some of it finally gave way exposing some of its contents.

The above picture is what remained on the door at this point. Meanwhile some of the floor became littered with the nest fragments. I also spotted something resembling a grub or worm among the fragments. I continued to scrape until remaining piece of the nest fell down off the door.
