Upon donating to the Museum, Blathers the curator will say:

"Rainbow stags have the honour of being called the world's most beautiful stag beetles, eh wot? Even the insect's belly has this rainbow design, making it one of the less vile bugs I've encountered. In fact, this may be the only insect whose underside I can view without retching..."

It can be found on a cedar tree to the left of the top terrace in the insect exhibit.

In New Leaf
"Rainbow stags are called the most beautiful of stag beetles because of their metallic-rainbow color.  Not only are their wings a pretty rainbow color, but their bellies are as well.  They are quite laid back, but they can be seen every now and then fighting to protect their territories."

Further information
The Rainbow Stag beetle gets the name from its unique colouring, which appears to change colour when looked at in different angles and in different light within its also unique, metallic-looking body. It is native to Japan, New Guinea and northern Australia.

When breeding and raising these beetles, they do not require special lighting if placed near a window. The temperature should be around 22 °C (72 °F). Their unique 'antler's only found in males are primarily for digging through rotten wood and for fighting. On some occasions they may flip their opponent a great distance into the air as they are considered very strong for their size.

Larvae have very strong jaws for biting through wood, and as a result should be handled with care as they are capable of painful bites.

Trivia

 * The Rainbow Stag Beetle is one of the few bugs that Blathers will not overreact to. He even says that he can look at it without fearing it.
