 Bumblebees generally visit flowers that exhibit the bee pollination syndrome and these patches of flowers may be up to 1 – 2 km from their colony . They tend to visit the same patches of flowers every day , as long as they continue to find nectar and pollen there , a habit known as pollinator or flower constancy . While foraging , bumblebees can reach ground speeds of up to 15 metres per second ( 54 km / h ) .
