Lucanus Posted September 9, 2013 Report Share Posted September 9, 2013 I originally thought that females have narrow tip of the horns while males have thick blob tip. But after couple of disections, I found out that my method was wrong. So I need help getting my Phileurus to be sexed. Can someone provide some pics and instructions on sexing these guys?

Dynastes Posted September 9, 2013 Report Share Posted September 9, 2013 You may be confused or looking at a very small male. How about some photos of the horns and lower abdomen? If the horn shots in your photos posted in the picture section include both specimens you have two males. Quote Link to comment Share on other sites More sharing options...

Lucanus Posted September 10, 2013 Author Report Share Posted September 10, 2013 Specimen #1 Specimen #2 They are pretty equal in size So how do I sex these guys? Quote Link to comment Share on other sites More sharing options...
Dynastes Posted September 10, 2013 Report Share Posted September 10, 2013 Are you saying the left specimen is not a female? Quote Link to comment Share on other sites More sharing options...
Lucanus Posted September 10, 2013 Author Report Share Posted September 10, 2013 Are you saying the left specimen is not a female? Nope. I thought it was a female until I dissected it. Turned out it was a male. Quote Link to comment Share on other sites More sharing options...
Dynastes Posted September 11, 2013 Report Share Posted September 11, 2013 Do you have a picture of its lower abdominal segments (side or/and bottom)? Quote Link to comment Share on other sites More sharing options...
Lucanus Posted September 11, 2013 Author Report Share Posted September 11, 2013 Do you have a picture of its lower abdominal segments (side or/and bottom)? I took off the abdomen from the specimen but I can still take the pic of the bottom. Quote Link to comment Share on other sites More sharing options...

Dynastes Posted September 11, 2013 Report Share Posted September 11, 2013 When you find a female you'll notice a distinctly different, v shape to the segment below the pygidium. It is strange to see a decent male with feminine horns. Quote Link to comment Share on other sites More sharing options...
Lucanus Posted September 11, 2013 Author Report Share Posted September 11, 2013 Looks like I'll have to check other dried ones to see the ventral sides. Quote Link to comment Share on other sites More sharing options...
Lucanus Posted September 12, 2013 Author Report Share Posted September 12, 2013 I think the pair of P. truncatus I caught in the summer are indeed male and female instead of being two males. Supposedly female : Supposedly male : Quote Link to comment Share on other sites More sharing options...
Dynastes Posted September 12, 2013 Report Share Posted September 12, 2013 In your other thread you appear to have a bunch of shots (6) of the male's horns close up but only one further away shot of the possible female's horns and none are labeled (such as specimen 1 and 2). All 6 shots of the horn closeups are the same specimen? The abdomen shots above could look different if the shot was taken at a different angle or they might be male and female. It's actually really easy to sex them in person but camera angles and unexplained photos make it difficult. Phileurus truncatus have specific requirements for egg laying, unlike the valgus and illatus. Quote Link to comment Share on other sites More sharing options...
Dynastes Posted September 12, 2013 Report Share Posted September 12, 2013 Also, if you don't get eggs before October you have to wait till next summer. Quote Link to comment Share on other sites More sharing options...

Their last segment is distinctive from each other so I guess I have a pair. What requirements do they have? Quote Link to comment Share on other sites More sharing options...
LarvaHunter Posted September 12, 2013 Report Share Posted September 12, 2013 Yes, what are the specific requirements for egg laying? Plus size of container that should be used. Quote Link to comment Share on other sites More sharing options...

Lucanus Posted September 16, 2013 Author Report Share Posted September 16, 2013 ewwww mites!!! you should clean them lol These mites are, apparently, gamasid mites which are somewhat beneficial to beetles. Quote Link to comment Share on other sites More sharing options...
LarvaHunter Posted September 20, 2013 Report Share Posted September 20, 2013 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 Quote Link to comment Share on other sites More sharing options...
LarvaHunter Posted November 6, 2013 Report Share Posted November 6, 2013 How's the grain mite population now? I'm curious if it worked. Quote Link to comment Share on other sites More sharing options...
