Breeding Prosopocoilus giraffa

I have a 112mm male and a 50mm female in a basic ten gallon tank, with 6 inches of dirt and wood chips mixed in. With a 6 inch breeding log inside. I feed the pair banana and apples. They just started eating at the end of last month and they emerged in September. Is there anything I should do extra??? Should I put multiple logs inside or a larger log??? Thanks, any info is welcomed

oh by the way, I'm living in UK (Birmingham) right now with one of my friends. I'm leaving in two months and when I leave I'm only bringing back the dried adults).

I also want to know:

There adult lifespan

And how many eggs I can expect

With nonnative insects most people here probably won't be able to give you as much info as you'd hope for. I'm sure some people here do know about their set up but I think looking into some foreign insect boards would be the best choice for help with this.

I would say that you may run into some trouble trying to bring back the dried specimens though since it would not be going through a USDA inspection facility.

Naaah! Dried specimens? I've been buying for years. You can even buy from large suppliers, no problem.

 
While I was in Taiwan in January, I got to visit some beetle shops and chatted with the owners. I saw an amazing variety of exotic beetles and one of the species was Prosopocoilus giraffa. The owner of the store told me that they live around an average of 10 months as adults, but breeding reduces their life span significantly--especially the females. You should be able to expect at least a couple dozen eggs if not more as long as there is sufficient room for them inside the container to dig around without damaging eggs they've already laid. The breeding container held a good amount of sawdust with as many logs as could fit inside. They were buried with just a little bit of the surface exposed and the total depth of the substrate was at least a good 8 inches.

 
It's necessary to wire the jaws of the males of the more aggressive species unless you have enough females that you aren't worried about losing a few. I would be less worried about Prosopocoilus giraffa harming the female than a large Dorcus species. I got pinched by both while I was in Taiwan, and I have to say that P. giraffa is pretty harmless in comparison to something like a Dorcus titanus. I'm pretty sure that wiring his jaws shut would not have affected his ability to feed but I don't know if prolonged periods of being wired shut might cause damage.
