I caught a foundress bumblebee queen in my backyard a couple days ago (she was excavating a hibernation chamber). I successfully managed to get her to hibernate in my standard yellow jacket hibernation setup (a small tupperware with dampened cotton and dry tissues/paper towels). Even though I have all winter to prepare her founding chamber, I still have no idea how to collect the right pollen. From what I read, shaking flower heads and collecting tiny bits of pollen probably would not work (I would have to shake so many flower heads to acquire the adequate amount), so the best way would be to collect fresh bee pollen. Since there always are a ton of bees at the "butterfly bush" in my yard, I could always catch a few bees and take their pollen.
Since that method could be painful/stressful to the bees, I could buy pollen as well.
1. Should I collect wild bee pollen or buy pollen?
2. If I should buy bee pollen, where should I buy it from?
