Gosh, Judy, sounds to me like you need more chickens to take care of those grasshoppers. Eggs from free range hens have less cholesterol, less fat, and more of the good stuff and they taste so much better! Just pen them up at night.
I live in northern Indiana and grew up in Illinois and I’ve never seen a grasshopper like that either. Ours aren’t shiny and they don’t have such looooong ‘antennas’ and they spit brown stuff. As kids we called it tobacco.
