The potter without a kiln

Potter Wasps belong the in family Vespidae, and are related to Mud Daubers. So now you know as much as I do....except I am not sure if you have seen one, but they are quite unmistakable with their remarkable appearance, with that thin waist.

This one was buzzing around Tai O in October 2020.

These wasps are solitary, and are beneficial in that they hunt for caterpillars to paralyze and place in a brood cell, i.e., the clay-based compartment in which the wasp larva develops. Hence the name potter, and you may have seen these little pots around on door frames for example.
