Wasps Nest

Back in the summer and autumn I blipped, several times, this wasps nest when it was at the height of it's production, due to the very mild autumn and early winter the wasps were there quite late in the year. 

I am not sure if something has broken into the old nest or if the rotten tree has just given way to reveal this amazing structure.  I am not very keen on wasps but their building abilities are amazing!

The extra is to put the blip into context.
