Hi Candide
We have lots of hover flies around; a pollinator you see especially in the spring, sometimes more often than honey bees! It's a good thing to build something that attracts them.
We have honeybees, but here they are an exotic species.
We also have lots of bees around here that are not honeybees. Orchard mason bees are good, and easy to attract by building "houses" for them. Other bees will be attracted to similar houses.
