INTRODUCTION. 
: SomE Species feed upon Herbage, others live and feed upon the folid Parts of Trees, and 
arks. 
Some dwell in the Earth, or other private Receffes in the Day-time, and at Night come 
forth, and feed on Grafs, Flowers, €c. Others again feed on the different Kinds of Moffes, 
Heath, Broom, the Leaves of Trees, Shrubs, ec. 
Some feed upon the Waters naked and expofed, and others make themfelyes Cafes of Sticks, 
Ruthes, €§c. inthe Waters, where they get their Food. 
Of the Forms of CaTERPILLARS. 
“PT HE Variety and Beauty which prefent: themfelves to our Eyes in the Form and Co- 
louring of Caterpillars, are no lefs remarkable than the Fes themfelves, as the Reader 
will be fatisfied by examining the following Plates. . 
Of the Change of CarErpitiars into the Chryfalis State. 
W HEN a Caterpillar has fed its appointed Time, and is come to full Maturity, it un- 
dergoes a Change, and becomes a Body of a different Form, incrufted with a Shell, 
and ufually called a Chryfalis or Aurelia; the Shell of which is formed underneath the Skin 
of the Caterpillar, which Skin comes off as foon as the Aarelia becomes perfect. 
Of the Curysanis or AURELIA. 
U RING its Continuance in the Chryfalis State, it feems to have no Senfe but Feel- 
ing ; and fome of them have even that in a very low Degree, for they may be touch- 
ed pretty roughly without moving. . Bey 
Tue Chryfalides or Aurelie of the Butterfy-Kind are all very beautiful ; fome of them look 
as if they were fludded with Gold ; fome are ftriped, others fpotted, and others mottled with 
all the various Colours of the Rainbow. But thofe of the Moth Kind are not fo; differing ve- 
ry little from one another, either in Shape or Colour, except the Magpye, and fome few be« 
fides. 
How the Aurelia or Chryfalis is fecured. 
OTHING in Nature is perhaps more deférying Notice, than the many different 
Methods whereby Caterpillars conceal and fecure themfelyes whil# in th 
is helplefs 
and unattive Condition. . 
Some of them fpin a large Cafe of Silk in Form of an Egg, wherein the Chryfalis lies con.» 
cealed, till the Time comes for the Fly to make its Appearance, which it does by piercing 
through this Cafe. 
OF fuch Cafes there are feyeral Sorts, different in Form and Colour:
