The Mexican Jumping Beans are exclusively inhabited by the Jumping Bean Moths.

Jumping Bean Moths are widely known for their larvae which inhabit the insides of the Sebastiana Pavoniana tree's fruit, also known as Mexican Jumping Beans. They are known for bouncing, or 'jumping' in warmer climates.

The female moth lays eggs on the flowers of the shrub. They hatch and the moth larva makes its way into the capsule of the fruit while it grows.

The larva eats the seeds and makes an exit hole in them. A hole is also made in the shell wall, from where the adult larva gets out if it ever crosses the pupal stage to become a moth.

Most larvae die inside the fruit, but some make it out, only to mate with the opposite sex and start the breeding process all over again.

The way the pod bounce is interesting. When they become ripe, the pods usually fall on the ground and will disintegrate and turn into three Mexican jumping beans.

Under the influence of heat, the Jumping Bean Moth larva inside curls and uncurls, colliding with the walls of the capsules and causing the bean to 'jump'. If an adult moth makes it out, it only lives for a few days.

When the eggs hatch into larvae, they force their way into the pods and eat the seeds. The movement of this moth larva makes the beans jump after they fall to the ground.

The larvae mature into pupal, adult moths which are beautifully monotonous in color.

How do they communicate?

The Jumping Bean Moth Range also includes, apart from its native Mexico deserts, the states of Sonora, and Baja California, as well as the Gulf of California.

The Jumping Bean Moth life cycle often goes incomplete, as the immature larvae do not make it out of the fruit as adult moths most times.

The Sebastiana pavoniana plant has green leaves which become red in the winter. Just like the moth, the Sebastiana pavoniana shrub is also native to Mexico.
