In December 2000, I visited the Insectarium in Philadelphia. I bought a mug in the gift shop which had a lump of clay painted to look like a cockroach on the bottom of the mug.
In 2014, I started regularly producing pottery, including several inspired by the mug from the Insectarium.

I made another series of cockroach cups in 2018:
