The Moths and Butterflies 



away to some crevice in the bark or sheltered place on the ground, and 

 there pupate. In two weeks the moths issue and deposit eggs on later 

 apples for the second brood. The larvae of this brood are tucked away 

 in the fall and winter apples when gathered, and are thus carried with 

 them into cellars, warerooms, etc. They soon issue from the fruit, and 

 finding concealed spots in the cracks of barrels or boxes or elsewhere 

 near the stored apples, pupate, the pupae lasting over the winter and 

 the moths issuing about apple-blossoming time the following spring. The 

 pupae are protected by thin papery cocoons of silk spun by the larvae. The 

 remedies are effective, but must be carefully and regularly used. Spraying 

 the young fruit with an arsenical mixture, as Paris green or London purple, 

 soon after the blossoms fall and again in about two weeks, will reduce 

 immensely the possible loss. Banding the tree with strips of old carpet or

sacking at the time the larvae are crawling out of the apples and hunting 

 for concealed places in which to pupate, will enable the grower to trap and 

 destroy thousands of them and thus greatly lessen the numbers in the second 

 brood. All fallen fruit should be promptly gathered and destroyed in such 

 a way as to kill the larvae inside. 



An interesting insect closely allied to the codlin-moth is the Mexican 

 jumping bearv-moth, Carpocapsa saltitans (Fig. 547), which lays its eggs 

 on the green pods of a euphorbiaceous plant of the genus Croton. The 

 hatching larvae bore into the growing beans in the pod, but do not attain 

 their full growth until after the beans are ripe and hard. The ripe beans 

 with the squirming larvae inside act as if bewitched, twitching and jerking, 

 rolling over and leaping slightly clear of the table or desk on which they
