The Bee Orchid
You know how when you're looking for a place to eat, you favor busy restaurants over empty ones? You're curious about what all the fuss is about, right? Well, the bee orchid figured it could use the same marketing technique, so it evolved a flower that's a dead ringer for a lady bumblebee. Male bees are intrigued by the mystery girl and try to mate with her, thus pollinating the orchid. How delightfully deceitful.
