I don't know how much you've looked at 10-minute weight measurements of
colonies over time, Charlie, but in an environment such as mine, where
colony weights hold steady this time of season, I suspect that it would be
very easy to detect a loss of an appreciable amount of the foraging force
in the morning, compared to baseline values and control hives at both
locations.
