Do Bees Have Knees
Do flies have knees or just elbows?
Hahaha, I like this question ... I don't know if you're kidding or if you're serious ... If you're serious my answer is:
In fact, there are no knees or elbows, in the link below you can find all the parts that make up the legs of a common insect (all three are the same). In bees, the difference is that the hind legs have a lot of hair where the pollen comes from (see link 1). This, for example, solves your doubts.
