I just took the egg cases out of diapause. So you should see hatching in next 20 days. I have about one mantis case hatch out on daily basis. Had about 50 Oxyopsis gracilis hatch out, and 5 Brunneria borealis or American stick mantis yesterday. Can't wait to see whats waiting for me tonight. I also mate mantis on daily basis to, so always something hatching, mating, or getting eaten.
