Roach Question

[Spider Tyrant]

I read that it was possible to tell the difference between Male and Female Madagascar Hissing Cockroaches based on a horn-like lump on the heads of males. Could I see a good picture of what this looks like?

That shows pretty good. There is a lot of pictures on this site of male/female hissers as well.

also, if you want to sex them before they mature and get the pronounced "horns" you can check out the bottom tergites. see this post
