“Airborne Organism” Identified [PDF]
Nature, 1970 IF the authors of the recent report1 had chanced to include an insect physiologist among those consulted about the unusual objects detected by electron microscopy in an atmospheric aerosol, their quest would have been at an end ! These structures are brochosomes, bizarre excretory products of the Malpighian tubules of leaf hoppers (Homoptera; Jassidae).
