In Fig. 16 is shown an orange leaf with a severe infestation of purple scale, which are shown in twice their natural Fig. 16 Eggs for the first brood arc deposited in the early part of March by the female under her scale at the posterior end of the body, which shrinks as the eggs are laid, until only the dead and shriveled remains of the body, are to be found under the anterior end of the scale. The eggs are oval in shape, whitish when freshly laid, but soon turn puq^le. They are to §28 CITRUS FRUITS IN GULF-COAST STATES 21 be found under the old female scale, where they hatch in about a week into small, six-legged, pale-colored creatures, oval in' outline, but flat. These crawlers are provided with eyes and antennae as well as legs and other organs of well-developed insects. They are barely visible to the unaided eye. The young crawlers avoid the light, which leads them to crawl under other things on the leaf such as the woolly white fly. A favorite location also is under the dried calyx of the fruit, where the insects puncture the rind. The young crawlers find a satisfactory place within a few hours after they are hatched and insert their sucking mouth parts, or beaks. The female remains stationary throughout her existence. If the female insect is forcibly torn away from her feeding place, she cannot reinsert her beak and perishes from hunger. The male insect is winged when adult and can move about. In from 8 to 20 days the insects outgrow their scales and produce a new scale, by a process known as molting. The old scale is not discarded, but on the co
