It's called an Eastern Lubber Grasshopper... They contain a toxin that may make you sick, so don't touch them. They usually have a black stripe that doesn't appear until they mature.
If you don't like insects on your corn (or other vegetation) I use tobacco juice. I mix a pouch of Red Man in a gallon of water and allow to sit overnight. It makes a concentrate that you can mix (about 1/3 juice-2/3 water) and spray on your plants. For some reason insects hate tobacco and this makes a great non-chemical insecticide.
Wow! Thanks so much for the info. I've only got one of these critters and I remove him from the plants. I just kind flick him away, I'll be more careful now. I'm not using any insecticides natural or otherwise so that the bees and ladybugs can do their thing.
For some reason, the tobacco doesn't seem to deter the bees. ladybugs seemed to like it better in the house for some reason lol!
