The Japanese have just raised the first captive-bred Dynastes hercules over 170 mm.

This will only happened in japan and no where else in this world where you will find national news on Dynastes hercules.

Wow! That is huge. I wonder what the biggest wild male would measure up to. What lucanidae25 said about a beetle making National news in Japan is so true, because beetle breeding is so popular there. I wonder how the breeder got one so large? Did he feed it some kind of special diet during the larval stage? The news reporters probably covered this but I don't speak Japanese, so I wouldn't know.

Good diet, good animal husbandry, or selective breeding aka Gregor Mendel?

I believe the biggest wild male is 173 mm and was up for sale for something like $25,000, I can't remember the exact figure.

The horn does not look natural. I have to wonder if it was manipulated somehow before it hardened. Straightening a curved horn can add some length, and that even looks stretched since it gets smaller in diameter and then larger. I don't know if stretching is possible but it sure looks that way, and straightening is definitely possible. This is regarding the 181mm specimen.

Yeah I thought it looked a bit weird as well.
Still a huge specimen...

I'd like to think that selective breeding will result in one the size of a suitcase that will sit on your lap and threaten intruders. More likely though we'll wind up with glow-in-the-dark striped pink with six horns, like the aquarium hobby.

I've heard that giant cockroaches have been raised in controlled experiments where the oxygen levels are higher than atmospheric oxygen is today. The experiment tested the hypothesis that higher levels of oxygen in prehistoric times was a contributing factor in allowing insects (such as dragonflies) to grow to enormous sizes. Does anybody know whether anybody has raised beetles or leps in a higher-than-normal oxygen environment? It seems like the Japanese would jump on this.

I don’t think one can rear insect in higher oxygen level to achieve larger size. They would simply get poisoned. It needs millions of years of adaptation, oxygen level didn’t drop from one day to another.

Paul K,
The experiment was done recently. The high oxygen level didn't kill the bugs. It simply made them larger.
