To be honest, we're all about anything that wants to pollinate wild blueberries. I was in a blueberry field with the tech team from Nova Scotia, and it was a rainy day. It was pouring rain. I had them there and I wanted to show them what strong hives look like during pollination, but it was a terrible day.
As it was, there were bumblebees flying around. The problem with bumblebees.... Kenna MacKenzie was a researcher at the station in Kemptville. She said that yes, bumblebees are good, but one nest has only 30 or 40 adults. They're a far better pollinator than honeybees, but there are only 30 adults. She said my hive there had 20,000, 30,000 or 35,000 bees in it.
It's the sheer numbers, and remembering that we only have a short bloom period. It's just like that, and then it's gone.
