Insects injurious to fruits . on thel(!!jf. Fig. 330 shows the larva, of natural size, on the fruit at a ; 6, an enlargedview of one of thesegments of itsbody, showing thehairs with which itis adorned. Themoth, of the nat-ural size, is seen atc, while at d an en-larged outline isgiven of one pairof the wings. The larva reachesmaturity about thetime of the ripeningof the raspberry, when it is about three-quarters of an inchlong, of a yellowish-gray color, each segment being furnishedwith several short prickles. It has the habit of disguisingitself by attaching to its thorny projections tiny bits of vege-table matter, such as the anthers of flowers, bits of leaves, etc., and by this means it often escapes detection. When full grown, the larva forms a slight cocoon, withinwhich it changes to a chrysalis of a pale-yellow color, withbarker lines and spots, which in a few days produces theperfect insect. The wings of the moth are of a delicate pale-green color, crossed by two lines of a lighter shade, and, when expanded^. ATTACKING THE FRUIT. 3^7 they measure about half an inch across. The body is greenabove and white beneath. As the larva of this insect is not usually observed untilthe fruit is ripe, no poisonous applications to destroy it couldbe used, and resort must be had, if anything is done, to hand-picking. One species of parasitic insect is known to prey onit. No. 186.—The Flea-like Negro-bug.Corimelcena pulicaria Germ. This disgusting little pest is not at all uncommon on riperaspberries. Its presence may be discovered by the fruithaving a nauseous buggy odor, but the insect is so small thatit is often taken into the mouth un-noticed until the disgustino; flavor revealsits presence. In Fig. 331 we have amagnified outline of this insect, the smallersketch at the side showing its natural size.It is of a black color, with a whitish stripealong each side, and is furnished with apointed beak or sucker, with which it punctures the fruit andextracts its juices.
