( 'arpocapsa pomonella. 



This is the most generally injurious apple insect, 

 and is probably known wherever the fruit is grown.

 hatches a minute 

 worm or caterpil- 

 lar, which nibbles 

 at the skin of the 

 fruit and eats its 

 way toward the 

 core. Here it con- 

 tinues feeding as 

 the apple develops, 

 increasing in size 

 until at the end of 

 three or four weeks it is about three -fourths of an
