Found this big bad beetle boi on my porch the other night. It's a Xylotropes Gideon aka Thai fighting beetle (my fav animal)! Looks like our dogs had already found him and roughed him up a bit. He was writhing on his back covered in dirt, but these things are built tough! 
I put him in a plastic bin with a longan (we have longan trees in our yard and they're everywhere this time of year). I left the top open so he could leave at any time.
When I checked in the next morning he was still there going to town on the fruit!
By the time I got home from work that same day he had stripped the longan down to the seed. He's free to leave anytime he wants l, but I guess I got a new pet now!
In all likelihood he's probably already mated and is just living out the rest of his days in peace.
Here's a close up of my Rhinoceros Beetle pal using flash. Did you know that they have perfectly spherical eyes? Also they are actually a dark red, not pure black. And they're quite hairy!
I think they have really cool/cute faces. Rhinoceros Beetles are just one of the coolest designs nature has ever come up with!
