I SEARCHED FOR 'TAENIA CYSTS'
This came from the Stanford U. website, the image didn't paste in.
The cysticercus larva completes development in about 2 months. (2)It is semitransparent, opalescent white, and elongate oval in shape and may reach a length of 0.6 to 1.8 cm (2).
These cysts travel inside the body. I've never seen one in feces.
