"Fieldnotes," September 15th & 16th, 2013: "Grasshoppers," by Leeann Drabenstott / Caroline Kurtz. http://www.montananaturalist.org/
"Males attract females with mating songs produced through a process called stridulation. A stridulatory peg on each of the hind legs is scraped against a raised vein on each forewing, creating a song or signal that is particular to each species. While grasshoppers are often considered destructive creatures, I prefer to think of them in the words of John Muir as "a crisp, electric spark of joy.""
