Here's a great article provided by C. Nolan, that might just directly relate to a future project of Pope Siglericus XXX. Fascinating stuff!
Parasite turns host into bodyguard
A new study describes yet another strange case of apparently parasite-induced behavioral changes: a creature that turns its host into its own, suicidally devoted bodyguard.
After the parasitic wasp Glyptapanteles completes an early life stage as an uninvited guest in the body of a caterpillar, the caterpillar exhibits stunning changes, according to researchers. It stops eating and stays close by the wasps, which by then are cocoons. It wraps them in a protective web of silk and defends them against approaching predators with violent, relentless head-swings.
