HOUSEHOLD AND STOREHOUSE PESTS. 343 



They hibernate in tlie larva state, the larva spinning a light 

 cocoon in the cavity of the fruit, etc., upon which it has fed. 

 Early in Spring they change to pupae, and in about fifteen 

 days the perfect insect emerges. The eggs are laid on the 

 fruit while in the course of drying, esijecially .such as is dried 

 by sun heat ; but often in fruit while it is getting ready to be 

 packed, or after packing, if the package is not moth-proof. 



Fruit in sacks has not any protection, as the moth can 

 deposit the egg through the cloth. If the fruit is packed in 

 boxes, and the boxes have not close joints, the moth deposits 

 the eggs in the seams, and the larva as soon as hatched makes 

 its way to the iruit in the package. 



In January last (18So), I received a small box filled with pits 

 and decayed parings of apricots and peaches, which were infested 

 by the larvse of these moths — the ]3erson sending them mak- 

 ing the inquiry: "Are they the larva? of the codlin moth?" 



In September, 1881, a choice lot of dried plums, pears and 

 peaches were exhibited at the State Fair, neatly packed in 

 thirty pound boxes with glass covers (the fruit was dried by 

 artificial heat). It was placed on exhibition in a fruit store 

 until the following Spring. In one of these packages of plums 

 under the glass I found seventy-three moths which had emerged 

 from chysalids in the fruit. 



At present I have specimens of what appear to be two 

 different species, but they may be merely varieties of one spe- 

 cies. The larva measures from five to eight lines in length, is 

 of a bright yellow color, and tapers slightly tow^ard each end ; 

 stomata, faintly bordered with brown ; head deeply notched 

 above, yellowish-brown ; cervical shield yellowish-brown. The 

 larva is slender, and from its tapering form can be readily dis- 

 tinguished from the larva of the codlin moth. 



Perfect insect. No. 1 (Fig. 353, Plate 4) ; length of body, 

 nearly four lines ; spread of wings, nine lines ; color, head 

 and thorax dark reddish-brown ; fore-wings, inner third yel- 

 lowish-white (forming a bar across base of wings when at 

 rest), balance of wing to apex dark brown, with two oblique 

 blackish stripes and blackish dots, the darker parts sprinkled 

 with whitish scales ; cilia, ash-brown ; hind wings, silvery 

 white ; cilia, darker than the wings.
