This absolutely fantastic beetle is a male HERCULES BEETLE, a species which in the wild is mainly found in the rainforests of central and south America.  I have named him Hercules which, whilst unimaginative, seemed the best choice!

You can see from these pictures that the Hercules beetle has absolutely HUGE horns!  These horns are mainly used in battles with other male Hercules beetles, during which they will attempt to pick their opponent up using the horns and to slam them down to cause the other beetle damage. 

These fights are usually over females, which do not have the horns and do not take part in such duels!  It is said that the male Hercules beetle is one of the strongest animals on earth for its size because apparently it can carry an object over 800 times its own body weight!!

As well as having very impressive horns Hercules beetles also have beautiful elytra (outer wing cases) as you can see below:

Despite their large size and relatively heavy weight these beetles can fly, but thankfully Hercules here seems quite reluctant to do so.  This is a good thing because whilst it is undoubtedly quite an impressive sight to see the flight of a beetle so large, they are not exactly the most graceful of fliers and are likely to bash into something (wall / window / person's head) which would not be ideal at all!
