INTRODUCTION 
Some are long, and drawn out toa Point at each End; others are more round. 
Tue Texture of fome is very thick and clofe. 
Oruers are thin, like Gaufe, infomuch that the Chry(alis may be feen thorough them. 
SomE Aurelia are white, fome yellow, and others of different Hues 5 and moft of the hairy 
Caterpillars intermix their Hair amongft the Spinning. 
Some Caterpillars form a hard-crufted Cafe, compofed of filk Threads glewed together, in 
fach Manner as to become hard like an Egg-fhell, fo that when the Fly comes out, a round 
Hole like a Door appears. 
Tue Silk-fpinning Caterpillars are of various Kinds, and depofit their 4ureha in different 
Places, and in different Manners, vz. fome faften them on the Leayes and Stalks of Plants, 
without any Covering ; others fpin the Leayes over them ; Others lodge them in Holes and Cre- 
vices ; and others im the Earth. : 
Many of the Afoth-Kind place their Chryfalis in the Earth, about an Inch or two deep, 
furrounding it with a Cafe of Earth lined: with a glutenous Matter, that no Wet can pene= 
trate: And what is very furprizing, notwithftanding the extreme Delicacy and Tendernefs 
_ of the #/y when firft bred, be the Ground never fo hard,, it makes its way thorough it without 
ruffling a fingle Feather, 
Few, if any, of the Butterfy-Kind form a Cafe or Spinning, except what faftens the Tail 
and Body of the Chryfalis. Some hang perpendicularly downwards, and others in an horizontal 
Pofition, being faftened by the Tail, with a Thread round the Back and on each Side. 
are fecured within the Leaves {pun together ; others are hid in the Hollows and Ba 
Trees; and others again under the Copings of Walls, in Houfes, Sheds, &c. 
Of the FL Y. 
A FTER the Chryfalis has remained its due Time, the Fly burfts the Shell wherein it 
was contained, and comes out formed perfectly in every Part, exeept the Wings, which 
then appear too fmall to cover its Body. In this naked Condition it crawls up to fome con- 
venient Place, where its Wings may hang down without any Hindrance : And when thus 
difpofed, the Wings begin to expand themfelves fo much, that in the Space of half an Hour, 
the Wings (of Burterfiies) are ftretched commonly to their full Size; nay, even thofe of the 
largeft Moths feldom require above an Hour’s Time. At firft they are flabby, like wet Paper, 
but foon afterwards they become ftiff, and capable of fupporting them in their Airy Flights, Ge. 
In this //y State their firft Care feems to be the Propagation of their Species, for fome of 
them will copulate immediately if they can find a Mate; to feek which the Male Butterfly 
takes Wing, as foon as his Wings are in a proper Condition: But few Ldoths, whether bred 
in the Night Time or in the Day, ever offer to fly till the Night after their Birth 
they go in Search of the Females.
