I was walking home from the lab, when I saw this utterly motionless dragonfly perched on a signpost. I looked at it closely, and there seemed to be something unusual about it –the back of its head was gone, with a sharp boundary at the eyes. It looked like it had been surgically snipped out, but that seemed so improbably, I thought it had to be some kind of illusion.
Then I touched it and it flew away.
I keep telling everyone, in case of a zombie insect invasion, they have a ventral nerve cord, so aim for the throat, not the top of the head.
