Checked my swarm traps last Sun & saw a couple of bees around one. Just a couple. This AM when I checked there were definatly bees there, so I waited til almost dark to go pick it up. The thing must have been 50 lbs. No telling how long it had been occupied. Moral: don't just glance at your traps, take a good look. Tomorrow I've to cut the comb loose & tie it into frames.
