It can put its leg up over its head if it wants to. Next to the little coxa and trochanter is the longest and largest segment in the grasshopper's leg; I suppose nobody remembers its name.
Listen to little Nell,—"number three the femur stands."
So it does, and what a very useful femur it is!
If it were not for the long femur and the long, slender tibia, the grasshopper would not be a grasshopper—it could not hop at all.
Watch the grasshopper, and see how he uses those long segments to jump with.
First he draws the tibia close up to the femur—now he is off!
He just straightened those long hind legs out with a jerk, and away he went!
What do you suppose the two little sharp spines at the end of the tibia are for?
