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 bean-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
