there is more than one saint associated with beekeepers:
St Ambrose - patron saint of bees, beekeepers and chandlers
St Dominic - an Irish monk who was a disciple of Saint David, bees were an important part of Davids teachings and monasteries, Dominic was St David's beekeeper, when Dominic returned to Ireland, the bees tried to follow him, he had to return to David and gift the bees to him before they would stay. Bees feature strongly in the heraldry and history of st David's cathedral, so you could say David was also a patron saint of the bees
St Gregory - for opening the flowers
St Benedict for summoning the bees to the nectar
St Bartholomew - because his feast day coincided with the traditional day of gathering the honey
Karlampii/Harlampi/Harlambost/Karlambost - A Bishop and healer, who used honey and beeswax in his cures not really the patron saint of beekeepers but is celebrated in Bulgaria by bringing honeycomb and honey into the church and by baking cakes with beehive symbols on.
Saint Gobnait/Abigail/Debra - a beekeeping nun who saved the convent from raiders by setting her bees loose on them
