When you think of Bees, (as one does, occasionally), most people think of one species…the Honey Bee.
But did you know that there are over 20,000 other species of Bee? And that taxonomists consider bees to be a special group of wasps? (so the answer to the question above, is "both").
And that many bees lead more solitary lives than the honey bee? Here is the Ceratinidia bee, also covered in Pollen. Shown below with a honey bee in the foreground, which is much larger than this tiny bee.
