"Flying Salt Shakers of Death"

"Infected adults maintain or accelerate normal host activity during sporulation, enabling rapid and widespread dispersal prior to host death," says Kasson. [...]

In four cicadas infected with M. cicadina they found signs of a plant-derived alkaloid called cathinone, a compound similar to ephedrine. It's possible that the stimulant could have evolved in the fungus to keep their hosts' appetites down and give them a boost to get them through those long days of plague orgies.

Another fungal pathogen called M. levispora was also associated with raised levels of a tryptamine called psilocybin - the psychedelic compound in magic mushrooms. This one might not come as much of a surprise. There's good reason to suspect the chemical evolved in fungi as a way to suppress insect appetites, changing their behaviour in a dissuasive fashion.
