Comings and goings into a wasp nest

I was hovering about with my camera when someone warned me to watch out for the wasps. I was wearing sandals as usual so she was giving me a very sensible warning, and once I'd seen why I became intrigued. I'd never seen a wasp nest with such a large entrance and just nestling in the meadows vegetation. I chose this shot out of several options as it gave me a sense of ships passing in the night, coming and going about their business.
