I see this insect on the outside walls of the reception center from time to time. It's quite small, maybe no more than an inch long and it's solitary. I've never seen more than one at a time. What distinguishes it, at least for me, is the head, which can gyrate in all directions without having to move its body. In addition, the very funny goggle eyes have the same attributes. In the image you can see the eyes looking up at me, right from the top of its head!
