I've read lots of different opinions on what crickets like to eat, but which of these things is most beneficial to the mantis that ends up eating the cricket? I think I'm going to order fly pupae because the flies deliver themselves to the mantids and it's much more fun to watch them snatch flying bugs out of the air, but until they arrive and hatch, it's probably going to be crickets for a week or two. They're Chinese L4s and their bellies are getting huge now that they've started eating the crickets! Thanks for any ideas.
