In the years 2004-2006, flowering dynamics and nectar secretion of Phacelia campanularia A. Gray flowers as well as the insect visitation rate were studied in the climatic conditions of Lublin, Poland. The flowering of phacelia started in the middle of June and lasted for 1.5 up to 2 months. Full bloom occurred between the third and fifth week of the flowering period of this taxon. For the study period, the average weight of nectar produced by 10 flowers was 75.64 mg, weight of sugars 11.31 mg, while their concentration in the nectar was 20.2%. Among the entomofauna foraging on the flowers of phacelia, honey bees were predominant, with their proportion among the pollinators accounting for 84.8%.
