don't know about age but adult males have full wings while females have small wing stubs

I found this...

The larger nymphs are easy to sex. Look on their underside, at the last segment of their abdomen. With males, the segment is small and narrow. With females, the last segment is large, as wide as the abdomen. Males also have much larger wing buds.
I don't know how correct it is and I'm not about to go inspecting my roaches either.... my contact with them is strictly at the far end of 12 inch tweezers!!

Thanks for the advice! I can see in the adults that the female has much smaller wing buds, brighter colouring etc.

Btw, it looks like my adult females are carrying egg pouches. I am trying to build my own colony of Dubias as my beardies love them.

You can not sex dubia until their very last moult. until then they are identical, however after having their last moult the males have nice long wings and the females have wing buds it looks like they dont have any wings. but until they are adults u will never know.

if it has wings then it is fully grown. That is the male. The females are wider and bulkier but not as long.

For sexing, I sex all my medium nymphs (or atleast a handful when I have time), and put all the females into my adult box as a future investment. They are easy to sex. Adult sexing is wings or no wings. Nymph sexing requires looking at their thorax. See the picture in a previous post.
