I am sure that some readers view the presence of this cockroach in the colon to be just as repulsive as Gregor considered his “unhappy and hateful appearance.” But to quote Kafka, “The right understanding of any matter and a misunderstanding of the same matter do not wholly exclude each other.”” Editorial note: this is the second medical case we’ve featured with a colonoscopy revealing a cockroach in the gut.(The first can be found here.) Makes you wonder how many of us have a hidden roach right now… NCBI ROFL is the brainchild of two Molecular and Cell Biology graduate students at UC Berkeley and features real research articles from the Pub Med database (which is housed by the National Center for Biotechnology information, aka NCBI) that they find amusing (ROFL is a commonly-used internet acronym for "rolling on the floor, laughing").The patient was completely asymptomatic, and it was decided that no stool studies were warranted.The patient was discharged home with instructions to follow-up in the event of any GI symptoms.As the body, hind wings and mouthparts are not preserved in fossils frequently, the relationship of these roachoids and modern cockroaches remains disputed.The first fossils of modern cockroaches with internal ovipositors appeared in the early Cretaceous.

This evidence supported a hypothesis suggested in 1934 that termites are closely related to the wood-eating cockroaches (genus Cryptocercus).

I am certain this cockroach was lonely before its demise, for these arthropods are communal creatures that have complex social behaviors such as resource allocation.

Indeed, they leave chemical trails in their feces and emit pheromones for mating and grouping behaviors. Some male cockroaches have been shown to eat bird droppings from which they obtain nitrogen, which is then brought back to feed their young.

The cockroaches are an ancient group, dating back at least as far as the Carboniferous period, some 320 million years ago.
