Not to worry. They are completely harmless. That thing that looks like a stinger is just for looks. They don’t bite, and they don’t sting. All they do is eat your pepper plants. Taking it to school was a great idea. If you feed it leaves from the same kind of plant that you found it on, and put an inch or so of garden dirt in the bottom of the jar or whatever you have it in, it will eat until it is ready to burrow into the soil and then it will become a rather large and pretty moth. Good luck!
