Mexican Jumping Beans
Mexican Jumping Bean is the seed pod of a shrub named as Sebastiana pavoniana. These are not actually beans or seeds. It is section of a seed capsule. It begins to bloom in the dry and rocky slopes of Chihuahua and Sonora in Mexico. The mother moth lays eggs on the capsules of the shrub’s flowers. Once the eggs are hatched, the larva eats its way through the capsule. These capsules become brown and hard and have a bean-like appearance once they mature. The larva feed on the capsule’s contents. These jumping beans necessarily require larvae that are alive.
