62 BUTTERFLIES OF MAINE. 
an inch long, and blackish brown. On the top of the eighth 
segment is a light brown patch extending down on each side. 
The tubercles of the back are larger than the others. The 
head is now somewhat warty and depressed in the middle 
above. In six days more it molts again, after which it is 
one-fourth of an inch long, and much the same in form and 
markings as before. Five days after this molt, the larva is four- 
tenths of an inch long, and begins to construct a winter resi- 
dence. This is accomplished by cutting away the sides and outer 
end of the leaf, leaving a fiddle-shaped piece with the midrib 
through the center. It next draws up the edges by silken 
threads until the two edges are brought together, and the | 
seam woven together with a close mat of silk, and the entire 
inside of the domicile lined with silk. The stem of the leaf 
is also firmly secured to the branch from which it grows so as 
to prevent its falling to the ground, as it otherwise would do. 
In this silk-lined house or hibernaculum it now retires, clos- 
ing the door, and hibernates for the winter. In the spring it 
revives, and emerges after the new leaves are put forth, and 
feeds a little, and then molts its skin for the third time. It 
is now nearly half an inch long, of a reddish brown color, 
somewhat speckled and mottled with black, segments two to 
four yellowish. On the third segment is a pair of irregular, 
knobbed appendages of a red color. The yellow patch on 
the eighth and ninth segments is extended down the sides. 
In six days more it passes the fourth and last molt, being 
three-fifths of an inch long, and much as in the last molt. 
Two days later the colors begin to change somewhat, and at 
maturity the larva is one inch and one-fifth long. In about 
ten days from the last molt it spins a button of silk on the 
under side of a branch to which it attaches itself and changes 
to a pupa nearly an inch in length, silvery gray, with a 
prominent, rounded appendage near the middle of the back. 
Duration of this stage, about ten days. 
The butterfly emerges and is on the wing at this place dur- 
ing the last of June and the first of July.
