How to sex dubias?

[Kloster]

I just got a bunch of dubia roaches.
I want to start a colony so I want to feed off some of the male nymphs and give the females time to mature and reproduce.

I know that when they mature the males have wings and the females have stubs but when theyre nymphs all of mine seem to have stubs?

There is another thread on this forum that you will have to use the search function to find, but it has photos of the end segments of Blaptica dubia to illustrate the difference between the sexes and will completely help you out.

Just ran a search, sorry my beardie is hungry and I got impatient.

Thanks for the reply anyways.
