Four-spotted Nephus Nephus quadrimaculatus
It's not often I find a new species inside the house but it's happened a few times and this was one of them.

My next one was also at home, this time in a pheremone lure trap hung in the garden to attract moths (I didn't note down which lure I had in there at the time but I suspect that wasn't relevant to its arrival in there).
