I have hundreds of what appear to be miniature honeycombs all over the stucco of my house. They are grey in colour and are about 30-50 sq.mm in area, and less than 1mm thick. I believe they probably contained some form of larvae at one time, as most of the cells appear to have no top covering. They seem to be stuck with some form of adhesion, as a hose has a difficult time blasting them loose.
