Well, during the years I've had milkweed on my property, I've never once seen any bee trapped by the flowers or any bee with anything like that on it. But I do know that many of the herbicides, pesticides and GMO crops have wiped out billions of bees. I miss the bumblebees...only seen one this year. The honeybees were doing fairly well early in the year, but I've seen very few since June. When my sumacs bloomed this month, I didn't see any bees. Long ago, there used to be tons of them during the sumac blooming.
