This spider was probably doomed - there were many small-headed fly eggs on the stick that the spider is resting on. But there were two small-headed flies in its web, so maybe the spider will have feasted on the cause of its demise.
This thin mud structure had been built between a box and the wall. Many of the cells are stocked with spiders. In two of the cells, a single wasp can be seen. No movement was observed while I took the photos, before we replaced the box.
