What is mexican jumping beans?

Mexican jumping beans are a type of seed capsule that contains the larva of a small moth (Cydia deshaisiana). These beans are native to Mexico and are typically found in the Sonoran Desert. When the beans are heated or shaken, the larva inside becomes active and causes the bean to "jump" or move around.

The movement of the bean is a natural reflex of the larva that helps it avoid predators and find a suitable environment for development. Mexican jumping beans are popular as novelty items and are often sold in tourist shops as souvenirs.

It is important to note that the use of Mexican jumping beans as novelty items has raised some ethical concerns, as the beans are living organisms that may suffer from being handled and exposed to unnatural conditions. Some conservationists recommend avoiding the purchase of Mexican jumping beans in order to protect the natural habitat of the moth species that inhabit them.
