The larvae are pale green to reddish brown in color, with a dark brown head and a few sparse hairs rising from the head and body. The larvae of this in- sect should not be mistaken for that of the bud moth, which is a very abundant insect in Oregon found working in the buds. The larvae of this insect works on the leaves. Kemedies Should this insect become abundant at any time it may easily be controlled by an application of spray as used for the codling moth. Oleander Scale.—See Ivy Scale, this section. Oyster Shell Scale Lepidosaphes ulmi Linn. H. F. Wilson Probably as widely distributed as the San Jose scale, this insect is the cause of much injury to fruit trees throughout the United States. It is not supposed to be as serious a pest as the San Jose scale, but is of con- siderable economic importance. Entire trees are seldom killed, but oftentimes single branches will become so weakened from their attack that they will not pro- duce fruit and may die, and at times small trees become so stunted as to never grow into well balanced trees. Besides our fruit trees this insect infests a large number of shade trees, vines and bush fruits. The adult scales measure about one-eighth inch in length and are dark brown in color. In early spring these may appear grayish brown, due to bleaching by the winter rains. When present in large numbers the scales will overlap and assume vari- ous curved shapes.
