When full grown, the larva leaves the plant and seeks shelter under the earth, where it forms an oblong-oval cocoon (Fig. 372) of particles of earth fastened j^iG. 3/ . together with gummy silk, within which it transforms to a shining, brown chrysalis, which remains unchanged until the follow- ing season. When the perfect insect is about to escape, the chrysalis wriggles itself part way out of the cocoon, so that the moth when freed from the chrysalis shell may find no further obstacle to its exit. The presence of this borer in the vines is soon manifested by a sickly appearance and a drooping of the foliage, which, if the cause is not removed, soon results in withering and death. Whenever a vine becomes unhealthy, the stems should be examined, and cut into if necessary, to remove the lurk- ing enemy. The moths may be prevented from depositing their eggs by lightly banking up the young vines with earth, as they grow, as far as the first blossoms. When once the larva is within the stem, no other remedy than the knife is of much service. ATTAOKINa THE STEMS. No. 222.—The Striped Squash Beetle. Diahrotica vittata (Fabr.).
