76,000 colonies. A colonie is about 4,000 individual bees.

320 colonies at 4,000 are roughly 1,280,000 honeybees.

In fact BOBs are 10 times more effective than honeybees. They pollinate at a time where honeybees are still asleep.

And 4,000 is considered a small colonie. They go up to 70,000 and more in the right season.
