five times, at different periods of their growth, but alfo the 
Spider , the Bed Bug , and even Lobjlers and Crabs. This ufually 
takes up Several days. Afterwards, they proceed in the fame 
manner, enlarging their web, and extending their daily foraging 
excurfions, till benumbing winter confines them entirely to 
their filken habitation; they then not only fecure the general 
web on all tides as ftrongly as they can, to exclude impertinent 
intruders, but each individual fpins a thin cafe for itfelf: here 
they reft in a ftate of torpid feeurity, till the genial war mth of 
the fpring animates them afrefh, and informs them, that the 
all-bountiful Author of Nature hath provided food convenient 
for them. Thus apprized, they iflue forth in the day-time 
and in fine weather, as before ; but having acquired ftronger 
powers, and the foliage they have now to encounter being 
more tender, they become iefs fcrupulous in their feeding, and 
devour the whole of it. A difpofition to affociate continues 
with them till they have changed their laft ikins, when they 
ufually feparate, each endeavouring to provide in the heft man¬ 
ner for itfelf. At this period they are raoft expofed to various 
enemies, and moft frequently attacked by the Ichneumon Fly 
(vide fig. 14, 15.). We fometimes find a few continuing toge¬ 
ther to the laft, when each fpins a feparate web, in which it 
changes to Chryfalis : this ufually takes place about the begin¬ 
ning of June; here, in a ftate of perfedf quietude, it remains 
about three weeks, when it changes to the Moth we have 
already deferibed.
