Important and Interesting Facts about Jumping Beans

  1. After 2 or 3 months the jumping beans will stop jumping because the larva inside is changing into a pupa.
  2. About six months later, if you are lucky, you may see the moth emerge. Remember to keep them cool during this metamorphosis.
  3. If a moth emerges, take it outside and set it free.
  4. The moth will not harm the environment in any way. It will not eat clothes, like some moths do. It will not eat plants. Surprisingly, it will not eat anything. Your jumping bean moth got all the food it needed when it was in it's bean (seed pod). It will not lay eggs except in its native home in Mexico.
  5. A moth will not emerge from every jumping bean. Many larvae will naturally die inside their seed home. This is normal, so do not be upset. Order fresh jumping beans from
  6. The jumping bean "jumps" because it is trying to either move to a cooler spot or is responding to sounds and light. It holds onto the very fine web it has woven on the walls of the bean, and then pushes away with its lower body hitting the oppisite wall with its head. This transfers the energy to the bean (seed) and moves the seed a short distance. It is certainly amazing to think about how much energy would be required and how strong a larva must be to move his/her seed!
