Size: 3 to 4 inches

These were built last year. We did not see any changes until this summer. Then we noticed the holes one at a time over about two weeks. Did something take over the mud tube? Was the architect a mud dauber?

Moved from ID Request.

Yes, pipe organ mud dauber. These are wasp exit holes, and I see no evidence that another type of wasp added onto the nests. I assume that pupae overwinter in the nests before the adults chew their way out in the spring (or apparently summer, in this case).

Perhaps this was made by a Pipe Organ Mud Dauber

But it was made last summer.

But it was made last summer. Does it take that long to hatch?

Mud dauber nests don't quite

Mud dauber nests don't quite "hatch" like an egg. Much like a bird nest, the mud remains in the same standard shape long after the nest is uninhabited.

I think that other mud dauber

I think that other mud daubers might add onto existing nests?
