MrCrackerpants Posted July 14, 2013 Share Posted July 14, 2013 OK. So you are getting some with a bit of red on them too. This is what I am seeing in my culture. Quote Link to comment Share on other sites More sharing options...

MrCrackerpants Posted July 15, 2013 Share Posted July 15, 2013 yes a few of them are reddish! Cool. I love this species. Thanks for sharing. Quote Link to comment Share on other sites More sharing options...
ArtBug Posted July 16, 2013 Share Posted July 16, 2013 Thanks for posting this, Nicolas! I have these and I haven't been able to tell who's male and who's female. After seeing your photos - I think it's quite clear! I've been confused because it looks as though my females are gravid - yet I don't see a male in my tank that has the large "horns" that yours has. I'm going to double-check AGAIN and see what I can find out. I only have five of these buggars - so it shouldn't be too hard to sort them out!

SLE18 Posted July 16, 2013 Share Posted July 16, 2013 these are one of ghose strange creatures that dont need males to breed arent they? great looking roaches btw. the nymphs remind me of mine, but I can't get pics to compare (long story) Quote Link to comment Share on other sites More sharing options...
Nicolas Rousseaux Posted July 16, 2013 Author Share Posted July 16, 2013 ArtBug, when the males are immature, the horns are really small, and some adults males show smalls horns as well. To know the sex, you can look between the roach, the last segment is larger when it's a female. Exemple with Archimandrita tesselata, male on the left, female on the right: SLE18, I'm quiet sure that this specie needs males and females to get babies Quote Link to comment Share on other sites More sharing options...
ZOO CENTRE Posted July 16, 2013 Share Posted July 16, 2013 Sorry guys but IT IS NOT GROMPHADORHINA GRANDIDIERI! Quote Link to comment Share on other sites More sharing options...
Nicolas Rousseaux Posted July 16, 2013 Author Share Posted July 16, 2013 this is why it's labelled Gromphadorhina cf. grandidieri... They were verified by a friend who was working at J'ean Leclercs'insectarium, but I still have some doubts... I'm sent some pictures to Georges Beccaloni and I'm waiting for his answer to be sure of what they are Quote Link to comment Share on other sites More sharing options...
