I sent pictures of the black and yellow mud dauber recently, and then discovered the mud daubed nest – mud huts? – for the larvae – at least I think so since these were on the inside of my garage door and the wasp was captured in my house. Now the connection is clear. I have never seen this carefully constructed wasp nest before so thought this might be a nice addition for identifying this wasp being in the vicinity. The nest was too high for me to put a comparison measure in the picture, but the tubes are about 1.5-2 inches in length and about 1/3-1/5 inch in diameter. The tubes are sealed in these pictures. About a week later, the doors were clearly open and tubes empty. When my gardener removed them, he broke open the mud and they were nearly hollow with only one dessimated carcass of a spider at the very end of one tube. Fascinating!
