Puerto Rican Pink toe egg sac?

[AndrewZ757]

I have a Puerto Rican pinktoe and it has been acting oddly. I am unsure of the sex or age but it is in the browish stage. Anyway, it has recently started semi-burrowing and hiding in this shallow burrow almost always. Today i coaxed her out of it and she was clutching what seems to be a small egg sac. It is a ball about the size of a dime. I have not mated her or had her in contact with any other spiders. If she is indeed a mature female, is making an egg sac without mating normal behavior? or is it even an egg sac? She was very fat bellied and i was expecting a molt. now she has a tiny sized abdomina

l with no molt.

Hello
The PIC is a bit hard to judge from, I have had avics take their webs roll them up etc. I will take a shot and say a ghost sack ? Meaning not mated,so the sack would be infertile. Some females display this,for what exact reason I can't say.

I want to add as well,I have had specimens web up a prey item as well. This I have not observed as common behaviour,but I have seen it. So maybe see if you can get more pics,but don't disturb the T even if it is a ghost sack no one could say if the same stress to the T would apply.

It's a phantom sac that certain spiders tend to make once reaching maturity. The eggs would obviously be infertile though, but at least you now know she is mature.
She will either discard the sac or eat it eventually.
