This very determined wasp had a slightly strange choice of nesting sites! It decided to build its nest hanging from the head rest of a chair in my office (a 5th floor office, Southampton UK). It took the wasp ~3 days to build this nest, it would spend ~1/2hr building then leave via an open window for a while to collect more materials. As it showed no interest at all in the office occupents we let it get on with it for a few days and took a series of photo's. Though before going home for the weekend we waited for the wasp to go out and closed the window - I wonder how long it spent nocking on the window trying to get back in!!
