Abstract
Abstract Patterns in the activity of insect visitors to ‘Grasslands Pawera’ red clover were investigated in two dawn-to-dusk studies. Long-tongued bumblebees, mainly B. hortorum, were the most abundant positive flower visitors on both days. B. Terrestris was a frequent visitor but usually visited negatively, robbing nectar through holes bitten at the base of flowers. Honey-bees were less frequent visitors, despite the proximity of hives, and most robbed. Bumble-bees foraged for a longer period each day than honey-bees and visited flowers most frequently in the evening. A peak in the number of newly opened flowers occurred around midday on 7 February and the amount of sugar per red clover flower was higher in the afternoon when investigated in detail on 18 January. Foragers from a boxed B. hortorum colony nearly all worked the red clover.
