We often see these large black carpenter bees in The Dordogne region – beautiful black insects seeking nectar from the flowers.
They have relatively short mouth parts, as you can see from the photos, so are only suited to certain types of flower.
Glancing at a quick web search, carpenter bees have a bit of a reputation of ‘nectar robbing’ by drilling holes in the side of petals and avoiding pollination, and of being a pest that can be a threat to houses and gardens by making holes for nests in the timbers. I guess there may be some truth in this, but they are solitary nesters, and could the problem be perceived in part because of their colour?
