The caterpillar eats away the inside of the seed, but it leaves the seed wall undamaged. The caterpillar then builds a web along the inner wall. Apparently, the seed jumps when the caterpillar grasps the web and jerks its body vigorously. This helps scare away birds and other animals that might try to eat the seeds. Warmth - increase the caterpillar activity and jumping.
Jumping beans remain active for several months.
The caterpillar makes a circular lid by cutting through the seed wall. The caterpillar later forms a cocoon and begins to change into a butterfly. The jumping beans are packaged 3 beans to a package. The package is a one inch square clear hinged plastic jewel box. Minimum order of 100 dozen packages.
