Insects injurious to fruits . ing covered more orless with a white or yellow-ish-white powder. The eggs are said to num-ber from two hundred to fivehundred in each cluster, andare of a pale-red color. Thenewly-hatched larva is red-dish or brownish, with longand slender legs. As it growsit gradually changes, becom-ing darker in color and irreg-ular in outline, and it soon begins to excrete tufts of waxymatter along the back and sides, following which long, semi-transparent filaments appear. These insects first attack the leaves, usually along themidrib, and afterwards migrate to the twigs and branches,and sometimes attach themselves to the trunk. They spreadwith amazing rapidity on orange and lime trees, the trunksand limbs of which are sometimes so completely coveredwith them as to appear white; the leaves turn yellow andsickly, and if no remedial measures are adopted the treessometimes die. The insect has been found very destructiveat Santa Barbara, where it has probably been introduced withplants from INSECTS INJURIOUS TO THE ORANGE. 401 Fig. 411.
