there was a dragonfly trying to run into the windows at my work that got caught in a spider web in the process and it bit me when I was trying to save it >:(
googled to see if it was a bite or a sting and yep! the bloody bastard bit me, how rude.
Dragonflies do bite, and they will bite humans, but only if you catch one and it’s trying to escape or defend itself. And only the largest dragonflies will be able to break your skin anyway.
There’s other kinds of updrafts (as I’m sure you know, flying seems like an especially dangerous hobby if you don’t understand wind and airflow) and they can travel quite a long distance in higher currents. There’s a butterfly that gets up to like 20k feet.
