yea i speak japanese and he does say that it is megasoma vogti i dont feel like watching the whole thing but i wouldnt really say they are communal but rhino beetles in general do better in groups as larvae than stags. are you possibly trying to find out how to raise mega vogti and other native megasoma to adult?I believe this is Megasoma vogti and not Megasoma thersites in the video because the top horn on the pronotum resembles more of M.vogti as apposed to M.thersites.
The first photo will show a M.vogti screenshot from the video and the second photo will show a screenshot of M.thersites from online.
Notice how the top horn on the pronotum is less split on M.vogti as opposed to M.thersites.

i talked to a few people from japan abt it and they assumed thay the flake soil used is too nutritous so they told me to try second fermentation flake soil with little to no additivesYes, I am trying to find out how to raise Megasoma vogti and other native Megasoma to adult. Although, I have raised M.sleeperi which can be kept separate with no issues as opposed to M.vogti.
