I introduced a guidebook that gathered recent studies on stag beetles and rhinoceros beetles in the Japanese page of this post.  The publication of the book was accompanied by the exhibition that shows over 500 species of the insect specimens.  The reason why I introduced this book was that it explains latest studies in easy-to-understand way for non-academic people.

These images are uploaded by permission of the publisher.

I wish I could introduce the book to you in English as well, but it is only written in Japanese.  Therefore I supposed it might be better to introduce you these authors who provided their articles to the guidebook.  Most of the authors studies rhinoceros beetles and stag beetles in the academic field. You can check their studies somewhere on the internet.
