How to sex Phileurus truncatus?

ewwww mites!!! you should clean them lol

These mites are, apparently, gamasid mites which are somewhat beneficial to beetles.

Be careful they can multiply pretty quickly. They are not beneficial enough for me to keep them. They can crawl on your hand from the beetle, plus they make the beetle look nasty. That's my 2 cents. My 2 P. Truncatus are doing great without mites.

I'm having some grain mite problems right now so I was using these guys to see if they can act as a biological control. Seems to be working for now

How's the grain mite population now? I'm curious if it worked.

Alan, is there any way to sex the Larvae? Ive been looking at photos from Dynastes larvae. I can see some some with the opening, some without an opening and others that are difficult to tell because the body has too much fat. On the ones with an opening it almost looks like a tiny V shape. I would post some images but my cheap camera cannot take a good close up picture.

I actually don't know how to sex the larvae of these guys but I assume they can be sexed in same manners as most Dynastids by looking at the herold's organ.
