round white nest hanging in loft space in North London
No interactions present.
This would be built by a queen in the Spring.
The reason there were fewer wasps this year than in the previous thirty years was the way winter came back after a mild Spring had brought the queens out of hibernation.
They were well into nest building when the weeks of horrendous weather (Summer 2012) set in.
For this reason there are now many dead spring nests left to tell the tale.
