ceived that by a very accurate and delicate invest 
tigation, the rudiments of the future FJy may be 
detected in the Caterpillar, provided it be ex- 
amined but a very few hours before its trans- 
formation into the chrysalis. 
It is in the larve or caterpillar state that most 
insects are peculiarly voracious, as in many of the 
common caterpillars of Moths and Butterflies. 
In their complete state many insects are satisfied 
with the lightest and most delicate nutriment; 
some do not feed at all, while others, as several 
Beetles, Dragon-Flies, &;c. devour animal and

Some insects undergo no change of shape, but

We must now attend to a few particulars rcr

major ])art of insects have the head distinctly

from the borly ; thus forming three portions. The 
limbs in insects, as I before observed, are never
