can macropanesthia rhinoceros be sexed ventrally?

[musihuto]

i.e. do females have the last two segments fused like in a wide number of other roaches?

thanks!

Yes, the female has a big solid segment for the last one. The males have a TINY segment after the big one. If your not careful you could almost mistake them. If my husband hadnt stolen the camera for the day I would take a picture. Maybe Ill post one later

Look at the post from Carlos. This question on sexing roaches gets asked alot. Once you understand how to sex one specie, you can easily sex all of them.

Most of the roaches Ive seen you can see a BIG difference in that last segment. On the Rhinos its very small. The males last segment is SO tiny!! where the female has a big segment......the male has a big one, then a tiny one. If you didnt know what to look for... well. See for yourself. Male's on the right.

oh yeah, i can tell quite easily for archimandrita, blatta, baptica, blaberus, gromphadorhina, etc. i just wanted to make sure it was the same for macropanesthia (cuz it looks like i might have 4 males on my hands... )
anyways, thanks, i will dig'em up and check again!

cheers!
