I am familiar with two here, the bubble bee and the carpenter bee. I have never had bees bother any of my large staghorns, but when they are outside for the spring/summer, ants will sometimes take up residence in them. They are just the "sugar-ants" but when I bring them back in in the fall, I have to sprinkle a bit of Orthene over the basal frond area to rid it/them of those ants.
