last night my son and I were running our light traps in a new area and we caught a lot of a new type of grasshopper. I’ve never seen this type before and I think it is a Southern Mischievious Bird Grasshopper. We caught them in an overgrown field in southeast Louisiana.
The only grasshoppers that I know of that are toxic a Lubber Grasshoppers. The hopper you have there is not a Lubber Grasshopper. That nymph looks to be in a mature instar stage and could be from the genus Schistoscerca. I am not 100% about ID nymphs. I would keep this hopper until it is mature adult hopper then ID this hopper. Here is a good hopper link.
