This might be a long shot, but I've had two hissing cockroaches for nearly a year now. I bought them as small adults under the assumption that they were both female, as I was told. Well, the older of the two just molted and looks like it's grown some sizable horns.
I was hoping someone could give their opinion on if this is a male or not. This is the first time I've seen one fresh out of a molt, so it could just be the color throwing me off. I'll post a before and after photo. I really don't want babies, so I'm hoping I'm just seeing things.

Yes, that second pic is a male. Here is a pic of an adult pair.

Well great. :arghh: I was so sure they were both female as they've looked entirely the same up until now. The two pictures are the same cockroach, just a week between the two. Maybe I'll be lucky and the other one will decide to sprout horns as well :meh:

That second one is a definite male, if you can get a clear shot of the other hisser's last ventral segment, I can sex it for you, even if it's a nymph. :)

As others said, definitly male. Looks exactly like some of my oblongata males, Could always sell the babies if you find them, but either way that is a good looking roach :D

Well thank you! I don't really mind having babies, but I know the SO won't be thrilled. If he'd ever notice anyway :rolleyes:

Well here you go! The first is the male, and the second is his possible girlfriend. I'm impressed you can sex a nymph! They're so tiny :astonished:

Well as you can see in the picture, at the end of his abdomen the male has two small ventral segments, meanwhile the female, (which is indeed a female) has one very large last ventral segment. :) You can use this method of sexing for most Blaberids.

So yeah, you got a sexed pair! Prepare for tons of babies! :happy:
