Carpocapsa pomonella, Linn. The Codling Moth. 
This insect is becoming so com¬ 
mon and doing so much damage 
to apples and pears that to know 
its habits and how to circumvent 
it in its operations is one of the 
essential elements in apple and 
pear culture in order to ensure 
success. Though all who have 
eaten raw apples have seen the 
whitish worm that burrows at the 
core, the moth that is produced 
from this worm is not so generally 
known. 
These little worms or caterpil¬ 
lars are produced from eggs 
laid by a beautiful little moth 
that measures about three-quar¬ 
ters of an inch across the wings

inner two-thirds by numerous lines of gray and brown while near the 
end of the wing is a spot of dark brown, the edges of which a.e burn 
ished with coppery color. The hind wings are light yellowish brown 
with a shining lustre. These moths make their appearance from the 
middle of April to the fore part of June, varying with the seaso 
and the latitude, or about the time the young apples are about 
the size of hazlenuts. The females, after pairing deposits a single 
egg on each apple, until her stock of from two to three hundred 
eggs is exhausted when, her mission ended, she dies. These eggs 
are usually placed in the blossom end ot the fruit, but occasionally 
they mav'be placed in the hollow of the stem end, or Simp yg 
to 'the side of the apple. These hatch in a few days from the 
time deposited, and the young worm at once burrows into the
