European Fruit Scale or Curtis Scale Aspidiotus Ostreaeformis The female is circular or broadly oval in outline, dark ashy gray in color with paler margin; sometimes the scale is nearly white. The exuvia is central or nearly so, dark brown, usually naked and glossy. Diameter Vs of an inch. Life History The winter is passed by partly grown individuals which become mature early in the summer. The insect gives birth to living young which begin to appear soon after the maturity of the female. In this State they are apparently but one brooded. This scale has been recorded from a number of different plants, among them, the apple, pear, plum, peach, cherry, birch, poplar, horse chestnut, basswood, alder, haw, maple, aspen, oak, etc. It has been reported in this country from Maine, New York, New Jersey, Michi- gan, Ohio, Iowa, Idaho, California and several other states. In Maine it is most frequently found on large trees in old and neglected orchards, though we have records also of its occurrence on cur- rant bushes. Specimens the past season. Fig. 1.
