Yes Here in Glasgow too. My son's house is next to fields and he has them all over his doors and windows.Must be the unusually warm weather ,especially just now. They seem to be larger than normal as well. Good job they are harmless.
We've had this the last couple of years about this time, early September.......all the spiders in the garden decide they want to come into the house! Maybe the evenings are getting colder or perhaps they just fancy watching a bit of telly???
