Spotting

Hi all, Good suggestions - I think we have mud dauber wasps here and I believe that it is what this is...will go back this evening and observe for activity!

Looks like a Mud Dauber Nest. http://en.wikipedia.org/wiki/Mud_dauber

Can you tell us something about this? What it appeared to be made of, where it was situated, how big/small it was? Can you go back and take more pictures and see who goes in and out of those holes?

Could be some sort of wasp nest?
