Lifespan of a Praying Mantis


Nov 13, 2017
I know from reading around that a mantid only needs to mate once, and all egg sacs will be fertilized from that one time. My Chinese mantis lived wild until about 8 weeks ago, when she joined our family. 2 days ago she laid her first ootheca. Is there a possibility that her eggs will produce live offspring?

From the time we got her she seemed a bit strange, staying only on the top of her enclosure, paying little attention to her food, Etc. For the past two days she has been more lively then she has been for the past two months combined! Is there any difference in a female that is going to lay a fertile batch versus a non fertile batch? Knowing that her time May soon be up, I'd love to know if she'll be leaving behind some new Little Critters
