Here's a piece of paper I found with some notes on D. tityus:

Well, that's an interesting piece of information! I had no idea they could play the guitar. I do happen to have some other facts to share with you about this beetle.
The male Eastern Hercules Beetle can be told from the female by its robust horns and powerful attitude. It will attempt to pinch you by moving its head forwards and using its "nose horn" to grab at you. It doesn't hurt a whole lot but it is alarming. More usually, these horns are used to fight with other males over girls. Sigh... typical male beetle behavior. The size of the horn usually reflects how well fed it was as a little grub.
While they're usually green and black, they can also be a solid mahogany color, or one of their elytra (wing covers) can be mahogany while the other is green with black spots. Every individual has different spots, too!

Now if you'll excuse me, I'll be heading out... I'm going to go make some small guitars and see if I can't encourage some hercules beetles to start an indie band.
