"When first hatched they are very difficult to detect, but when full grown they are very white and, although only four-sixteenths to five-sixteenths of an inch long, are quite easily seen. Full-grown maggots have the peculiar habit, if taken out of the fruit and placed upon a smooth surface, of curling up and jumping from 1 to 6 inches. For the general appearance of the larva? see figures 8 and 9. a. The pupae.—After leaving the fruit upon which they have fed, the larva? either burrow into the soil to depths varying up to 2 inches or seek shelter under any object upon the ground and there transform to the pupa or chrysalis stage. During this stage the insect is not able to move and re- sembles the seedlike object illustrated in figure 9, b. Although outwardly appearing quite dead, inwardly the wonderful changes are taking place by means of which nature transforms the ugly maggot into the beautiful fly; and in the course of a few days the adult fl}- breaks forth from the pupa, pushes her way up through the soil, and, as the mother of a second gen- eration, flies back to the tree and searches for fruits in which to lay her eggs. INTERESTING FACTS ABOUT THE ADULT FLY. Fig. 7.—Cross section of peach showing general shriveling of walls of egg cavity and separation of eggs. Drawing made one and one-half days after eggs were laid. (Authors' illustration.). Incapable of inflicting bodily injury on man, the adult fly is, nevertheless, the fruit growers' most persistent enemy in Flawaii. for she is contin- uously searching for fruits in which to lay her eggs. Adults die within three to four days if they have Fig. 8.—Small m
