Definitely those BIG HUGE scary black buzzing bees. They are definitely not afraid of me. The wasps that like flowers and the normal, sane bees fly around while I garden, but those mean big black bees dive-bomb me. So I make like a tree and leave when those hovercraft come in for a landing They scare the bee-gee-bees out of me for sure. Why can't they share the garden like the other flying buzzers?
