MANY-DOTTED WORM AUTUMNAL BROODS. 243 



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 lumber 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 Noctuidse. 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 Tortricidje and the Order Lepidoptera. It is most 

 intimately related to a European species named semifuscia?ia i
