In a previous post I had talked about how you can tell the difference between male and female bees. Yes, male and female bees look different from each other. There are certain physical characteristics that you can use to tell them apart.
Do you see the difference between the bees in the above photograph? They are the same species or type of bees, the Blue Orchard Bee (Osmia lignaria), only the males have tiny white beards. The females lack facial hair.
Another characteristic that can be used to tell males from females is size. With bees, the female is larger than the male. Even though males are smaller, they can still grab a female and take her down during mating. Here is a photo of a male and female bee mating. The larger female is on the bottom with the smaller male on top.
So there you have it…co-ed bees.
