Sexing Nymph Hissing Cockroaches

[samfish]

Is there an easy way to sex 1-2 month old Nymph Madagascar Hissing Cockroaches?

I could not find anything on the internet.

I do notice that there seems to be two distinct body styles, some of them seem much longer and thinner, and some are much wider...

Females have a larger last segment. You should be able to do it at around 1/2 inch (sometimes less) once you get familiar with how they look.

The image here is the same no matter what the species is. It'll look a little different, but the female is always twice as wide: http://www.roachforum.com/index.php?showtopic=5634

Cool, works perfectly... The longer/skinnier nymphs were Male, the wider ones were female!

It doesn't always work out that way - depending on where they are in their molt cycle they can look either skinny or fat so it's not foolproof! I got lazy with my dubias that way and ended up with no males for a while. lol

OK- I will use the last segment to be sure!!! Thanks for the info!
