Fun fact, turns out they only decapitate mates while under stress from the environment, which includes being observed apparently.

For decades, Researchers thought it was the default behavior and were wrong, they were in fact causing it. Feels bad.

I recently stepped outside my front door to find a preying mantis hanging out. I left it alone. When I came back a few hours later it was still there, but it was headless. Took me a second to realize it was missing it's head. Guess he got laid while I was gone, lol.

so... no head?

Those are female mantis

This is what happens when you think with your “other” head
