This breed is also in Korea, It lives around 3-4 years, and has a extremly long life for a beetle.
You usually hibernate when you need to, in case you need to keep the beetle for next year breeding.
This method is ususlly used when making your own bloodline, because you would want to keep the one with the rare characteristics as long as possible so that you could breed it for a longer amount of time.
I'm not sure if it is making sense, but....
hibernation can be done by putting the male, and the female preferable in seperate enclosures, and staking up at least 20 centimeters of substrate.
This way the beetles could dig inside and hibernate more quickly and dont freeze to death...
You would need to put them in a cold place, usually below 19celcius, and they will start hibernating.
On breeding
You need a enclosure large enough to put the wood inside(breeding wood).
you put 4cm of substrate, and the wood, and cover with some substrate.
the wood needs to be prepared with special care.
You need to peel off any remaining bark on the wood, and any og the orange material left behid the bark on the wood.
This orange material is critical to the larvae's health, because it is known to cause the intestines of the larvae to pop out, and die.
once the wood is clean, you put in in the water for around 20minutes, and it is ready for the egg laying. This reed rather prefers it dry.
This breed always digs up on the wood, so its quite a mess when it starts laying eggs. but its also one of my favorite, because its very pleasing to peel out the wood to find the larvae and eggs.
