Fertile Ootheca?

[plerny300]

I found this Ootheca in my backyard about 2 weeks ago, it’s around an inch and a half and I don’t know if it’s fertile. I’m assuming it isn’t because it’s really small, but I suspect it’s a Carolina mantis Ootheca.

It"s a Chinese ooth and it appears to of hatched.

I think @hibiscusmile is right.

I ordered some fertile Chinese mantis ooths on Amazon recently, and they were quite a bit smaller than an inch and a half.
