Weird mantis ootheca

[Arthropod Universe]

My female ghost mantis who matured back in October and never mated just made a really weird ootheca she is really old and I don’t know what I should do with it. Should I feed it to some isopods or anything or should I try to hatch it

If she hasn't mated it will be infertile ( however there are some species that can just make more without reproduction) she will most likely make 2-6 before death, I'd try feeding it to isopods

She hasn’t made anymore and she probably will expire soon which is what surprised me cause she has never done this before for the past 3 months she’s been mature
