How do Mexican jumping beans jump?

Inside Mexican Jumping Beans looks like tiny worms, but they are actually moth larva. Female Jumping Bean moth called Laspeyresia saltitans lay her eggs on capsules of a desert shrub native only to Mexico, and after they are hatched, they will eat its way inside the flower's capsule. Over time the capsules turn brown and hardens. Once trapped inside these capsules, these larva/worms eats the developing seed inside the shrub's capsule moving for food for several months, until it become still or dormant as the worms/larva begins to spin a cocoon inside the capsule during their metamorphosis state, until a moth emerges.
