B.Dubia breeding and reproduction question..

im curious as to why it extends the eggs at all IF mating is internal? maybe its a way to regulate the temps, if it gets too hot, its extended, if its cold, its kept inside...im quite curious :) wouldnt it be pointless to lay the eggs and suck them back in if nothing is done to them, unless theyre moving them to another area where they will be incubated and formed, other than the area they were made?
 
Im starting to really wonder how the hell they do it

this is what i see

i keep finding ooths that have been dropped..i see them for about a day, then they dissapere, and about two or three weeks later i see more nymphs..so im assuming they drop the ooth for fertilization?? im still confused on how, and why..

heres the pics i got..

1st pic is ooth with a male near by.

2nd is the ooth it self..in good condition..no bites or anything

3rd is a pile of nymphs

4th is just the group i have

This is my set up.. About 30 Adult Females and 15 Adult Males and 700 or so mixed nymphs.

Dubias mate and are fertilized internally. The ootheca is formed and then it is released to be sucked back into the "incubating chamber". I believe the exposure of the ootheca is to regulate the temps. I also believe if one is found "loose", it is most likely infertile. If it "disappears", it was probably eaten. I read once mated, the female cannot mate with another male. something about the male "plugging" her up or something and she will no longer be receptive to other males, until after the birth.

Thanks, seems spot on.. I also found this on the internet.

"Lifecycle:Mating occurs when the male deposits a sperm packet in the female. This sperm packet inhibits the female from further mating.
Females then lay an egg sack, they then pull this sack back into themselves to incubate ovovivoparitally.
Gestation is about one month (28 days).
The babies hatch inside the female. Between 20 and 40 live young, each about 2 mm long, are produced in each clutch.
Babies mature in about 4–6 months depending on temperature and food supply.
Adults live 1–2 years."

well i understand now..soo weird..im amazed they are soo easy to breed and they do all that work..
 
My colony is starting to really explode since I moved them to a smaller bin and upped the temp a bit. Not much to do for them, except provide heat and food.
 
Nice.
Your chameleon looks good man!;)

Ive yet to find any fresh nymphs like that.
By the time I see them they are dark and scattered everywhere...
 
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?

Hi,

This is called thermo-regulation.

The female dubia coolscthecegg case off from time to time during the incubation. It is normal behavior.

Hi and welcome! :) That is interesting to know (I’ve seen my discoid with their egg case sticking out), but this thread is ten years old. The op hasn’t been active since 2015. However, we always need knowledge about our feeders.:)
 
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.
If you stress them as when cleaning the bin they sometimes drop the case. That's a waste obviously
