I watched this spider build it's web outside my window at night a few weeks back and she hasn't left! She only seems to come down onto her web at night (which has meant some very hot nights as I'm too terrified to open my window!). Taking a photo I noticed how shiny she was/the dimpling/markings on her and thought I'd try and work out what it is. I think possibly a false widow looking at some other pictures, but thought I would ask here if that seems right?

Sorry for the pretty rubbish pic- without the flash you couldn't see detail.
