And FYI to anybody reading, the best thing you can do for bumblebee populations is to grow wildflowers native to your region and don't cut them down before they flower so the bees have a chance to get to them.
Bumblebees are these fuzzy, gentle, fat little guys. They're fun to watch and harmless, as long as you don't try to go catching them with your bare hands or something like that.
Some wasps look scary but all they want to do is hang around the flowers.
