what a job they have been doing on european paperwasps
around here! for a few years I had thousands of nests..even in my cardoors they would squish in and try..but I have watched these tiny things march right up to the nests and lay eggs..and seen whole nests destroyed and this year I have my "normal wasps" and very few European paperwasps and they are under siege. I think the native paperwasps know them and fight them off and the invaders don't.

 
moths and Polistes
Well it looks like they have quite a job ahead of them if they want to conquer the European Paper Wasps around where I live. The wasps are currently winning. Our nuthatches are doing their best to pick off the larvae from wasp nests around the eaves but I think they're picking on Polistes fuscatus instead of Polistes dominula. I've hardly seen any P. fuscatus this year but P. dominula are doing well.
