INSECTS. 



The Codling-worm. Carpocapsa pomonella. This insect 

 is in every orchard in the land, and does more injury to the 

 apple crop than any of the others ; yes, probably more than all 



the others combined. It 

 is a tiny creature, so 

 very small that it has 

 never been seen in its 

 winged state by the 

 great majority of fruit 

 raisers, whom it has rob- 

 bed of tens, if not of 

 hundreds of dollars. In 

 some seasons, fully one- 

 half of the fruit is so 

 marred and eaten out by 

 this worm that it is not 

 fit to be sent to market. 

 It is an European insect 

 that has crossed the ocean and taken possession of the orchards of 

 the new world, an invader not so easily driven out. At Fig. 30, 

 a represents the moth, with its wings expanded, as when flying, 

 and h the moth when at rest. It is a beautiful little moth, the 

 expanded wings not extending over three quarters of an inch, 

 but the fore-wings are crossed with numerous grey and brown 

 lines, giving them the appearance of a watered silk, and near the 

 hind angle of each of the fore wings is a dark brown, oval spot, 

 edged with a bright copper colour. The hind wings are a light 

 yellowish brown, as lustrous as satin. These moths, during the 

 month of July, deposit their eggs on the young apple, in the cavity 

 at the blossom end of the fruit, and, as if to destroy the value of 

 as many apples as possible, they take care to lay but one q^q on 

 each apple. There are occasional exceptions to these rules ; they 

 do sometimes deposit a second egg in the cavity where the stem 

 is inserted, but these exceptions are met with just often enough 

 to prove that the parent moth intends to deposit only one egg on 

 each apple.
