They have muscles, too, to move their little bodies with.
We have muscles under our skin, you know. The muscles move our arms and legs and bodies.
If you clasp your fingers around your arm and then move your arm, you can feel the muscles.
The insects have muscles inside their chitinous shells. The muscles move their bodies.
The muscles are very, very strong.
They are stronger for their size than the muscles of a horse.
John, do you know how heavy a load a horse can pull?
Well, it cannot pull a load equal to the weight of its own body.
Now, listen to this,—almost any insect can pull a load that is five times the weight of its body!
Ah, yes, some insects can pull a much heavier weight than that. The honey bee, for instance, can pull a load twenty times as heavy as its body.
