B.Dubia breeding and reproduction question..

Ok well everything I read states that B.Dubia give live birth to their nymphs.

Well I have never witnessed this, but I do see clusters of fresh white nymphs when cleaning the bin sometimes.

I have been seeing a few females with what looks like a egg case attached to their rear. I caught one once and places her into a deli cup to try to observe first hand what would come of the egg case. I woke up the next morning and could not find any egg case, nor did I find any nymphs. My only conclusion was that she ate it/them.

Well I got a pic of one last night.

Can someone explain what exactly that "egg case" is? and how reproduction works with B.Dubias . Do they emerge from this "egg case", or do they give birth one by one to live nymphs?

Yep, she is laying her egg sack and then will suck it back in and incubate it until they hatch which from what I understand is about a month.
 
Ahhh!! Thanks all!!

This explains why there was no trace of the ooth from the female i took out and placed into the Deli cup. I just thought she ate it.

You learn something new everyday. This i didn't know about the sucking it back in to incubate deal.

I agree.


I have never seen mine mating either.

I have scoured the internet.

All I can find on their reproductive process is:
Keep them warm, they will breed like crazy.
They give live birth.

:rolleyes:

So much for some in-depth info...

I have also done my fair share or searching and I also found that YouTube video. It seemed to be at the end of the process. A process I was not seeing in my colony. But I was seeing a lot of what I posted in the pictures. I also got the vague " heat =numbers" deal. I learned a lot from this thread. Keep the info coming.
 
It seems all roaches create an oothecea.
Some store it until it hatches, some store it for a period of time, and some dump it asap.

My question now is that does the dubia roach deposit the eggsack, then pick it up and then it gets fertilized?

Or does it mate, then drop it, and then pick it up?

And to what purpose would it deposit, then pick the ooth back up?

So now we have goals...

EDIT: By "deposit" and "drop" I mean the point where it extends the ooth.

Also, is it just extended for mating?
