this one is what is on the bottom of the first pic:

on the same wall, ialso have the long vertical tubes, open at the bottom, with exit holes chewed out on the side surfaces.
thanks!

The common name of these wasps is "mud wasp".

Try searching:
mud wasp(s)
mud dauber(s)
sphecid
Sphecidae

The long vertical tubes are something else. I've noticed a large dark bee repeatedly going in between the shingles of my house, and there were long vertical tubes where the shingles were pulled away for remodeling.

on the top photo, the dark spots in the holes, are those larvae not sealed off yet? it is haard to tell by the photo, but there were things in there, but i didn't want to disturb anything.

daubers are ok, and i certainly have LOADS of spiders. i would prefer different smaler predatory wasps.
i did see a somewhat large blue-black wasp in the shed but not near the nests. unfortunately, i post before i search- my field guide has mud dauber as black and yellow. obviously there are different species, i tell myself...

thanks again!
