Common Evening Brown (butterfly)

The fluttering butterfly caught my attention. It had flown into a web and trying to escape. The Jewelled spider moved in but every time the butterfly struggled, it moved to the other end of the web. When the butterfly stopped struggling the spider came down and started snipping the web above it. I think as the butterfly drops, it swings into more web which would make it easier to wrap up. However this gave the butterfly an opportunity to struggle free. It lived to fly another day.
