You may have met this character before in a previous post of mine. His name is Daddy Long-legs Spider (Pholcus phalangioides). He is always in the same spot in my garage, hanging upside down at the base of the wall by the side door. He has chosen his spot well, for the ants have found a way in here, too, and the clever one here intercepts them on their path, picking them off when he fancies a snack.
For more information on this spider please visit the previous post Something Alien.
