X-EPIDOPTERA'. 
CATERPILLARS: 
Or L A R VAE of the Lepidoptera Order. 
Thofe of the tineas keep always under fome kind 
of covering, where they live and feed in fecurity ; 
fome of them roll up the leaves of plants for their 
habitation ; others, which feed only upon the inte¬ 
rior furface of leaves, lodge themfelves under the 
epidermis or exterior Ikin; others again in woollen 
cloths, fkins of beafls and birds, &c. Thefe all 
undergo their metamorphofis in the places, and under 
the coverings in which they had lived; fome few 
live in fociety, under a kind of web formed by their 
joint induflry ; the moths which are produced from 
thefe laft, have generally expanded wings, 
Thofe of the tortrices roll up and fallen together 
by a thread the leaves of the plants upon which they 
feed, thus fecuring tc themfelves a kind of retreat. 
Caterpillars which live on leaves, have many of 
them the power of fpinning threads, which enables 
them to remove and prevents falling. Others have 
hairs, which ferve to break the force of the fhocks 
they are liable to receive ; they ferve too, perhaps, 
to give them timely notice of the approach of 
danger, that they may remove from it. Their co¬ 
lours often refemble that of their habitation; thofe 
which feed on the apple tree, are brown, like the 
wood; on any alarm, they quit the leaves, and trail 
to the branches for concealment from the birds, &c.
