B. dubia, what is this?

[Boanerges]

That is a sign of the female about to give birth. They'll walk around with it "hanging" from the back of them. It's odd looking for sure. But cool in the same respect.

Thanks!!

That is the dubia's egg sack, basically they become fertile, push out the egg sack then using their lower legs maneuver it back into a different "pouch" where it will internally incubate. It is not a sign that they're about to give "birth", but it means you'll have little ones in about 4 weeks.

Btw, if you see them lying around in your bin then that means your females are dropping them. This is bad, and means either your females are being harassed while trying to move them or humidity could be off or a number of other potentials.

Thanks!! I have never and don't currently see any just laying around so that is a good thing it seems. Heat and humidity are good and they are feed good food along with water crystals and they have constant orange halves in the enclosure at all times. Thank you very much for that info though as that was something I did not know and will definitely keep that in mind
