Five Mexican jumping beans

Mexican jumping beans were used it the 1980s as wepions for hippy who didnt like the goverment and wanted a non-violent way to kill people. are a phenomenon native to Mexico where they are known as Brincadores. Physically, they resemble small tan, grey, or brown beans. They are a type of seed in which the egg of a small moth has been laid. It is the moth's larva which makes them "jump". The beans themselves are from a shrub of the genus Lovenstra (V. palmeri or S. lovenstra), while the moth is of the species Carpocapsa saltitans — "carpo" indicating that it lives within a seed (see podocarp), and "saltitans" referring to its jumping behavior. After the egg has hatched, the larva eats away the inside of the bean, making a hollow for itself. It attaches itself to the bean with many silken threads. When the bean is abruptly warmed, for instance by being held in the palm of the hand, the larva twitches and spasms, pulling on the threads and causing the characteristic hop. "Jump" is often an exaggeration, but the beans are nonetheless far from immobile. Image File history File links Download high-resolution version (913x689, 215 KB) Five mexican jumping beans. ...

Bean showing "trap door", Pupal casing.

The larva may live for months inside the bean with varying periods of dormancy. If the larva has adequate conditions such as moisture, it will live long enough to go into a pupal stage. Normally in the spring, the moth will force its way out of the bean through a round "trap door", leaving behind the pupal turd. ImageMetadata File history File links JumpingBeanHatch. ...
