Insects injurious to fruits . nch in diame-ter, nearly round, of a dark-green color, with a smooth sur-face. In about ten or twelve days the eggs begin to changecolor, becoming darker, and growing very dark just beforethe escape of the larvae. The very young caterpillars areblack, roughened with small brownish-black tubercles, withthe first segment thickened, of a dull, glossy flesh color, aprominent fleshy tubercle on each side, and a patch of whiteon the seventh and eighth segments. When full grown, it appears as in Fig. 81. It is thenfrom an inch and a half to two inches long, with a ratherlarge reddish-brownhead, and a greenbody, which is thick-est towards the headand tapers posteri-orly. On the an-terior segments the green is of a darker shade, but paler on the sides of thebody, aud partly covered with a whitish bloom. On thefront edge of the first segment is a raised yellow fold, whichslightly overhangs the head, and from which, when irri-tated, the larva protrudes a yellow, fleshy, forked organ, at Fig. 84 INSECTS INJURIOUS TO THE APPLE. the same time giving off a disagreeable odor, which is doubt-less used iis a means of defence against its enemies. On eachside of the third segment is an eye-like spot, nearly oval,yellow, enclosed by a ring of black, centred with a smallelongated blue dot, which is also set in black. On the hinderportion of the fourth segment is another raised yellow fold,bordered behind with rich velvety black; the latter is seenonly when the larva is in motion. On the terminal segmentthere is a similar fold, flattened above, with a slight protu-berance on each side. On the fifth segment are two bluedots, one on each side, and there are traces on the hindersegments of similar dots, arranged in longitudinal under surface is paler than the upper, with a whitishbloom. When the caterpillar is about to change to a chrysalis,which is usually during the early part of August, the colorof the body grows gradually darker, until it becom
