Around the time I purchased my D. lobata, I also found a lot of Tenodera sinensis oothecae by my home (we moved). I'd spotted 20, and kept 10. I sold some, and hatched the rest. I released a lot of nymphs as well. I kept some for myself from 2 of the oothecae. Ferdinand, Paully, Cheech, Chong, Saunder and Mori.
Ferdinand was male and made it to adulthood. I'd tried mating him with Cheech but with no success (I was later informed by LAME that he'd read that related sinensis aren't usually interested in each other! And none of the males were that I'd had. Until I found a wild caught male, who mated with all my females plus LAME's all-popular female, Echo).
Paully was also male and made it to adulthood:
Cheech was female and made it to adulthood, and was never mated with, as the males refused:
Chong was male, and was the only one to actually penetrate Cheech. But only for about five second; he ended up jumping off quite quickly. I tried again a couple weeks later and Cheech had bitten through his thorax, and I was unable to save him after that:
Saunder was female and died at L6, the day after I fed her a cricket (puking, diarrhea). I'm not sure what it is, but I've had horrible luck after feeding my mantids crickets. I avoid them at this point.
I wasn't sure of Mori's sex but he/she died at L4, unexpectedly. No puking or anything. I just woke up and he/she was dead. I'd fed him/her a wild-caught cockroach the night before, maybe that had something to do with it? I took a photo of a black spot on her abdomen, wondering if that was related. And how it got there, and what it is.
(I'm sorry for posting such a sad photo of a deceased mantid but I'm hoping one of you may be able to give me an idea as to what that black spot is.)
