THE LESSER APPLE WORM. 47 
Table I gives the relative number of the two species as obtained 
from wormy apples picked from the trees, each picking including 
some windfalls, which would tend to slightly increase the percentage 
of Enarmonia larve. 
TaBLE I.—Relative seasonal increase of Enarmonia prunivora over codling moth larve 
in windfalls and in fruit picked from trees in orchard of D. S. Ballou, Siloam Springs, 
Ark., 1908.

a Enarmonia and Bpinotia larve were not separated in Tables I and II, as it was not possible to readily 
distinguish between them. However, there were very few specimens of Epinotia till late in the season, 
i. e., after the middle of August, and then in smal] numbers as compared with the number of Enarmonia. 
Table II, prepared by Mr. E. L. Jenne, is from wormy fruit picked 
from trees at intervals stated, no windfalls being included.

SEASONAL HISTORY AND HABITS. 
Information regarding the overwintering or hibernating habits of 
the larva of this insect is not yet complete. Overwintering larve 
have been found in cracks and crevices of the bark of trees, and 
also in fruit and barrels which had been stored over winter. Search- 
ing through the rubbish around the apple bin of a vinegar factory 
on March 24, Mr. E. L. Jenne and the writer found larve of Enarmo- 
nia at the rate of 4 to 135 larve and pups of the codling moth. A 
few days later 234 larve and pupe of the codling moth located from 
3 to 8 feet above ground were collected from the framework of the same
