Bugs?

This a detail of a wall on Liz' backyard studio. I saw it from a distance and thought "WHAT?" It looked as if the wall was covered with some kind of bugs. As I got closer I realized that what I was seeing was the remnants of ivy and the tentacles or whatever they are called, that the vine uses to attach itself to walls and things. I guess someone cleaned off most of the wall, but this one vine grew back. The bugs were what I saw first, but the single vine made the photograph.
