Added. Thank you Plazbo. Not sure about that wobbly apostrophe. All of the HelpMeFind Bees are spelt Bee’s, and I note Tantau uses no apostrophes at all. (Come in HelpMeFinders. How many bees does it take to make a paradise?)
Patricia, it depends on whether we are talking about honey bees (Apis mellifera) - thousands to ten thousands. Carpenter bees (Xylocopa), mason or orchard bees (Osmia) are solitary and happy singles except at mating time.
Being allergic to bee stings, and just bumbling around here, I’ll buzz off. (The HelpMeFind page for Bees Ltd, a nursery in Chester. UK is interesting.)
