LOL mine would take carolina locusts and boy would they thrash around as the mantid ate them, the mantids were unphased. I had the Chinese types BTW I had one really cute one that I would take evrywhere with me and it would just sit on my hand or shoulder.... wasps are no issue for them as some times they can take mice and bird. I don't condone feeding of live verts to captive mantids, the risk is too great and the nuts out there seem to glorify it. Which adds a bad rap to us mantid owners. In the wild as we all know is a completely differnt ball game.
