Hahaha, I love the mantids my friend and have posted some big ones in the past.
A study reflects that sexual cannibalism in mantids has to do with the eggs of the female, the males body material is passed into the female and thus she can lay more eggs. The male by virtue of his death provides nourishment for his offspring.

This world would be childless if human males were to do this hahaha

Great shots and a lovely description here.
Blessings!
