I love mantids!!!!
I got one of those things but a bunch of parasitic wasp larvae ate all of the eggs.
The same thing happens with all of the other mantids that I find at my house, they do well for a while and then "BAM!!!" I find it dead with a maggot crawling near it.
Don't think i've ever seen one of those. Are mantids related to the mantis? I've only ever seen one wild praying mantis it was back when i was in high school. I saw it on the wall in one of the hallways of all places. I tried to move it in order to rescue it, but it crawled to high up the wall.
