Sorry Leena, I think AZ is too hot and NY too cold. You probably didn't run into these nasty bugs.
But they're these huge insects that stay underground for seventeen years at a time and then all surface at once and mate like mad. Because they're only around one year in seventeen, they're effectively out of the food chain, so there is never enough predators to eat ALL of them.
Because of this, they are the dumbest bugs you'll ever meet, and they have practically no defenses at all, or even survival instinct. They won't get out of your way, they'll fly right into you, thinking you're a tree, try to climp to your head and start buzzing.
And they are LOUD.
Ugh.
