"So, naturalists observe, a flea has smaller fleas that on him prey; and these have smaller still to bite ’em; and so proceed ad infinitum."

July 3 - Raillietina cesticillus
Raillietina cesticillus is a common tapeworm of chickens and other poultry. The intermediate hosts of this worm, beetles but sometimes even houseflies, eat the eggs of the tapeworm, where they develop into cysticercoids. The chicken then consumes the insects while it is foraging. Large numbers can infect a single bird, as shown in the photo.
