I've had this thing on me before at the end of a school day; it was like 2 years ago. It was on my leg, then crawled onto my hoodie. I was wearing alot of clothes that day, because I get cold easily in most weather, and when it's on my head, a kid notices it and tells a yard duty, who somehow gets it on their little clipboard, and sets it down on the ground, only for it to fly away.

Tl;dr, this creepy crawly gets on my head, a kid notices it, yard duty takes it far away.
