neverspent | August 25: Mysterious mud pod (Reply)

Looking for signs of new growth on my tomato plants, I found an amazing and tiny piece of architecture built onto one of the branches of the young maple. It's made of mud, ovoid-spherical in shape, and 14mm long and 8mm wide. (Yes, I took my Disney World ruler out and measured it.) The most interesting part is the hole right in the center of the long side, with a perfectly formed entrance lip right around the hole. I couldn't think of what made this little hidey place. I've watched mud daubers at work before, and they can make that type of thing, but it's usually larger, tube-shaped, multichambered, and located under the eaves of a nice dry, dark barn or shed.

A bit of research turned up the potter wasp, and its nest does look like the one I found. Hello, wasp! Thank you for lending your architecture style to Native Americans for their pottery!
