their cocoons will also be met with at this date. Hence it ap¬ 
pears that some reach maturity and come out in their winged 
state a month earlier than others. 
The moths probably attach their eggs to the leaves, and from 
them comes another generation of worms the same year. These 
feed upon the leaves in August and September, and having en¬ 
closed themselves in curved leaves in the same manner, are with 
the fall of the leaves in Autumn carried to the ground, where 
they lie in their pupa state through the winter and hatch winged 
moths when the warmth of spring returns. It is quite probable, 
however, that some moths come from their cocoons late in au¬ 
tumn, and crawling into crevices under the loose bark of trees 
and similar situations, pass the winter in a torpid state, and come 
forth again upon the wing early in the spring — for freezing does 
not kill them, as is shown by the following fact. A worm hav¬ 
ing inclosed itself in an apple leaf the last of September, the 
leaf was placed in a tumber of moist earth and was kept in a 
warm room, whereby the winged moth was disclosed one even¬ 
ing in the latter part of December. The tumbler was hereupon 
placed out of doors, the night being intensely cold. Next morn¬ 
ing the moth within it was found frozen as hard as a stone; but 
on bringing it within doors, it thawed in a few minutes, and im¬ 
mediately revived, flying and skipping about in perfect health. 
’The larvae of this insect will be recognised with ease from 
what has already been stated respecting them. Worms however 
which have a most close resemblance to them produce another 
species of moth. When ready to change to pupae these bury 
themselves in the earth and are eventually changed to a larger 
ash gray moth pertaining to the Family Noctuidae. The two spe¬ 
cies are so closely alike when in their larva state that I have 
supposed they were but one. And I refrain from presenting a 
description of this larger moth and a full description of the lar¬ 
vae until more exact observations will enable me to state the 
marks by which the worms of the one species may be distin¬ 
guished from those of the other. 
The insect whose transformations have been narrated belongs 
to the Family Tortricid;e and the Order Lepidoptera. It is most 
intimately related to a European species named semifasciana ,
