Something is eating my bittersweet blooms.
Every year I see tiny little pre-berry blooms. When I go out to inspect them a few days later they are totally gone!! What would eat my berries or is there something wrong with my plant and they fall off. I had 2 full bloom berries this year!!!!

The berries are poisonous to humans but highly desirable to birds. I'm not clear whether you are seeing the flowers or actually the beginning of berries. You do need a male plant in addition to female plants to produce berries. There could be a lack of pollination causing blooms to fall off.
