Domino roach male:female ratio

Recommended Posts

About a year ago, a seller gave me a few Dominos as gift when i was purchasing other stuffs from him. Those quickly died but left me quite a few egg capsules. I left them alone for many months until I saw some movements in the substrate, and I started feeding them. Surprisingly (to me), I ended up quite a few of them.

Anyway, now I have about 20 adults, and still there are some nymphs under the substrate. They have been matured for over 2 months now, but I have yet seen any new egg cases. So I examined them carefully, and I couldn't find any females, they all have very long antennae.

So my question is that whether it is normal for Domino roaches to have a very high male ratio?

Cheers

Kenneth

Yes, however, there is another factor in your case. Males are also usually the first to emerge. Check the abdomenal segments on your nymphs.

Thanks, I really hope that some of the nymphs down there are females, I probably wouldn't bother them, I'll just keep my fingers crossed.
