Plant dedicated floral resources on farmland
In a replicated trial of flower-visiting insects foraging on six 0.1 ha sown patches of phacelia on farmland near Thessaloniki, Greece, 95% of all visits were by honey bees (Petanidou 2003). No bumblebees and only small numbers of solitary bees, mostly sweat bees of the family Halictidae (no more than six species in any flowering period, 12 species in total) foraged on the patches.
