A third generation follows in the month of September. This 
generation lays the eggs from which the larvae which appear in 
the following spring are hatched. 
The female, as has already been stated, is wingless, and lives 
solely for the purpose of oviposition. Having laid her eggs, 
which she covers with the hairy scales which she plucks from 
the abdomen, and mingles with a viscid secretion, which she 
deposits with the 
eggs, and which on 
drying becomes hard 
and brittle, she dies. 
The young larva on 
being hatched has the 
power of spinning a 
thin thread of silk, 
with which it lowers 
itself from its resting- 
place when disturbed, 
and by means of which it regains the place from which it has 
dropped. This power is lost as the insect develops after succes¬ 
sive molts. The mature caterpillar is a rather striking and not 
unbeautiful creature. The head is brilliant vermilion in color; the 
body is white banded with black, and adorned with black-tipped 
tufts and bundles of cream-colored hairs. There is considerable 
disparity in the size of the larvae and the pupae of the two sexes, 
as is partially shown in Fig. 183. The larva and the pupa of the 
female moth are generally twice as large as those of the male. 
The best means of combating the ravages of this insect is to 
see to it that in the fall and winter the cocoons, which may be 
found adhering to the 
twigs of trees and 
shrubs and secreted in 
the nooks and crannies 
of fences, are gathered 
together and destroyed. 
It is also useful to spray 
the young foliage of
