This saga precedes the formation of an egg case that will be attached to a twig to winter over in the garden. The female dies, and in the spring dozens of tiny mantids emerge from the egg case. Only a few make it through the summer and as we see, the males take part in reproduction at their own risk.
Much has been written on whether female mantids actually kill their mates, but in a back yard on Block 832 Tuesday I saw the evidence that it happens. And now so have you.
