This has to be one of the most interesting and by far the largest scarab I have every found!!
It is about 4-5cm in length (2-2.5 inches).
What made it even more interesting is the fact that when I picked it up it squealed at me!! LOL!! I was kind of shocked but have been told that many of the Heliocopris and Copris species do make these kinds of noises.
Thanks Adrian for the identification and information.
