Female Hardwood Stump Borer

I have never seen a bug quite this big before. I am also not quite sure what the "Stinger?" looking thing is. Any info?
thank you , Dolly Wade

Hi Dolly,
This is a female Hardwood Stump Borer in the genus Stenodontes. The stinger is her ovipositor. She uses it to deposit eggs under the bark so the larvae can burrow into the hardwood.
