These are leaf-rollers, and generally hide between two or more rolled-up leaves. Muchalarm was felt for a time and various poison sprays were tried, but withpoor results. Many trees were stripped of their leaves and growth,giving them a very ragged appearance. This insect has been with usfor some time and its appearance in such great numbers can be attributedto the mild spring weather with little rain. As soon as the caterpillarsmatured the damage ceased and the trees soon recovered their verdure. 5^>s.^ -fr»,,,-=»^ a. Egg
