Ef- So the majority of the swarms I witnessed were a healthy 2 pounds of bees. There is 3,000 - 4,000 bees in one pound. To answer your question on if these swarms or some of them could have been large orientation flights... that would be a minimum of 6,000 bees airborne and orienting. Would that be possible? Wow!
Riverrat - a 3 lb package is a little smaller than a football
Bsweet - I would compare it to a large grapefruit. depends on if they wear yoga pants or eat alot of fast food. Jim
