SummaryHoneybee colonies moved at night into new territory had smaller increases in weight than similar undisturbed colonies during the 7-day period following the move. Colonies moved out and back during the same night showed no such reduction in nectar storage. The difference was presumably the result of a need to reorientate to new pasture. Colonies moved in late autumn (November) showed a significantly greater winter consumption of stores than those not disturbed; those moved twice showed still greater consumption. Each move resulted in an additional consumption of 4–5 kg stores per colony between October and April.
