Jumping beans originate from Mexico. They are not beans but seeds of a shrub that have had an moth's egg laid inside. The egg hatches and the larvae hollows out the seed. The larvae wriggle inside the seed and cause it to move.
Under certain conditions the larvae can live inside the seed for several years before pupating and emerging through a hole it makes in the seed. The jumping bean moths belong to the genus Cydia.
Other names for (or types of) Jumping bean include:
