Butterfly sighting

Location: city of Wisconsin Rapids
Wood County

I saw the sulphur while driving through town. I was lucky to spot it among all the blowing leaves. I thought I would share some photos that I took this summer of a potter wasp and its egg chamber. This was the first time that I've seen one of their chambers. The photos of the open chamber and the wasp were taken on July 10th. That's also the date that the wasp provisioned the chamber with a caterpillar. The chamber was found closed on the 11th. I checked it every day, and I found it opened and empty on August 3rd. The chamber was 7/16 inch in diameter.
