Jimbe Posted November 19, 2007 Share Posted November 19, 2007 I want to know because in my small colony of dubias i only have one female so far and the rest of the adults are males and i have some nymphs. I'm getting some more dubias soon to increase the colony size Quote Link to comment Share on other sites More sharing options...
Zephyr Posted November 20, 2007 Share Posted November 20, 2007 I'm pretty sure that the last segment on the abdomen will be smaller in males and larger in females, but to see it on those leetle guys you'd probably need a microscope, or REALLY good eyes.

Jimbe Posted November 20, 2007 Author Share Posted November 20, 2007 thanks, my nymphs are quite big and I can see the last segment pretty easily most of my roaches are male hope fully I will have more females with my other roaches I ordered Quote Link to comment Share on other sites More sharing options...
