The wasp was dragging the Opisthoncus spider, which appeared to be paralysed, around the window frame. However, when it got too close to a hole hiding a Badumna spider, the big spider darted out and snatched the prey away from the wasp. The wasp tried to take it back, but the big spider retreated with it into its hole. The wasp ran all around searching and almost became prey itself when it got too close to the hole. The last photo was taken at the start, but shows the wasp better. There are mud nests all round these windows.
