Here is the mark maker in action.
The Black-and-yellow Mud Dauber (Sceliphron caementarium) working industriously.
The wasp begins making a ball of mud. Notice how the wasp uses its jaws and front pair of legs to form the ball, the middle pair of legs as a fulcrum, and the last pair of legs for "pistons" to tip into a head stand position. Fascinating process!

Once the mud ball is formed,
the wasp carries it with the front pair of legs as it flies away.
So, what's up with a wasp making mud balls? Check back tomorrow.
