No. I think not a spider...I have a dim feeling of what it may be but can't focus on it- very distant recollection, you see. The point is: to be on the safe side do gently rub it off togrther with any little critter lurking underneath... and don't hold back- phals have a tough texture. You have probably done this already!
BTW love the username- so lyrical and brings a smile. Cool!
