After several attempts to try to find some chinese nymphs from where I placed 5 ooths and had placed t hem in several wood piles and came to some conclusions as since I released them which was in june several factors could of came into play to prevent the nymphs maybe from survivng. Could be that there is a large population of predators such as birds,bees,snakes and spiders and such which maybe either erradicated the survivng population if any or lessening their numbers. Also it did rain quite a bit a few days after the ooths hatched and another conclusion is the rainfall may or may not have flooded the nymphs out but I just am not sure. I wanted to just see if any survived but the only mantis species that is dominant is the european mantis. I think my theories could associate themselves on any species that is released and also if a species is released in a area where there never a population of the species then the species may have to learn to adapt to that area or perish!
