Plants grown in shady places are usually most liable to attack. Generally the worms are surrounded by a light web, and occasionally two leaves are fastened together in order to give them protection. The insect never produces serious injury, but it is well to watch for it and take such steps to destroy it as may be practicable. It may be destroyed by pick- ing the leaves containing the larvae, but it is best to fumigate with hydrocyanic acid Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Galloway, Beverly Thomas, 1863- [from old catalog].
