j A tree in the Mexican swamps near j Alamos has a curious fruit, triangular I in shape and divided into three pods. Two of the pods contain small, blacic seeds; the third contains a caterpillar of the tortricid moth (Carpocapsa saltitans). The moth lays its egg upon the flower, and the part of the flower containing the egg grows as the seed pods form and ripen. When they are ripe in August they fall. The caterpillar thereupon coils itself in the form of a spring, and propels itself and the pod containing it in successive jumps from the tree.
