If the Spring is warmand favorable, the larva?are ready to assume thepupa or chrysalis form by the fifteenth of April. The duration of the pupa or chrysalisstate depends on external circumstances; if warm Springweather, the perfect insect may appear in from fifteen totwenty days, and may be prolonged to twenty or thirty Spring of 1881 has proven an exception. I found Mada-lene pears on the sixteenth of May in which the larvae hadmatured and left; also, on May seventh found a pear withlarva about eight days old. (This is about eighteen daysearlier than usual.) On the seventh of April, 1883,1 found anempty pupa case from which the moth had FIRST APPEARANCE OF THE MOTH. The moth generally appears from April 25th to the fifteenthof May—a few in favorable locations by April fifteenth. Thetime al5 which the eggs arrive at maturity apparently coincideswith the ends or terminations of the pupa or chrysalis state,so that the sexes are ready to unite soon after moths produced by the hibernating larvae deposit theireggs in the blossom end (or calyx) of the fruit, generally;possibly because they cannot puncture the epidermis (or skin)of the young fruit. Later broods deposit their eggs on anypart of the fruit. The eggs are attached to the fruit by a pastysubstance. It is rare to find more than one egg on any apple,pear, or quince, or more than one larva. The larva is hatched INSECTS INFESTING THE APPLE TREE 105
