Monobia quadridens (Four-toothed Mason Wasp)
I went out back today after work and found this little wasp on the mountain mint. I was only able to get a few half decent pictures of it before it flew off but they are good enough that I’m pretty sure it is a four-toothed mason wasp (Monobia quadridens). Like the potter wasp in yesterday’s picture, the nests of the four-toothed mason wasp are provisioned with caterpillars. The cells of nests are separated by mud partitions, which is why they are called masons. At least I think that’s why. Maybe they are members of the fraternal organization of a similar name.
