I think it is, but I'd like to be sure.

Wow
That is one badly parasitized nest! dominula seem to be more affected by this than other species are

 
now I'm interested too!
I brightened the image a bit to get a better look at the cells, it does look like there are silk cocoons or something in them. What kind of creature parasitizes wasp nests?

 
webworms!
a wasp keeper's worst night mare. they build their cocoons in the empty cells and take over the nest causing severe damage!

 
"Webworms"
...is a term used for a variety of moth larvae. Apparently Chalcoela is the moth genus that makes webbing in Polistes nests.

 
Thanks.
That's interesting to know. Maybe they can be used to control ''P. dominula'' where it displaces native species—but more likely not. :-)

 
never knew that!
Since wasps feed caterpillars to their young, I didn't think caterpillars would move into a wasp nest - unless it's safe there because it's the last place the adult wasps would look...

 
Interesting.
What parasitizes the nest, and where can I see it in the picture?

Yes!
It's dominula alright, the orange aentenna are a dead give away!

 
Thanks!
Good to know. So far they haven't objected to my using the same front porch they're using.
