spring. As they afterwards increase in size, they spread 
abroad in search of food; but their local attachment is 
very remarkable, for neither the caterpillar nor even the 
butterfly will stray from the place where it was bred. 
Numbers of the latter may sometimes be observed on 
wing, in a small spot of swampy or marsh land, when 
not one of them is to be met with in any of the adjacent 
places. As they fly very low, and frequently settle, they 
are easily caught. The caterpillars are generally at their 
full growth about the last week in April; when it takes 
place, they suspend themselves by the tail to change into 
chrysalids, in which state they remain fourteen days.— 
Their mode of suspension, is a singular instance of the 
extraordinary power of instinct. They fir^t draw two 
or three blades of grass across towards their top, and 
fasten them together by means of their silk: then hang 
themselves beneath the centre of these, each having it& 
own little canopy. By this means, they are not only 
hidden from the sight of birds, but defended in a great 
measure from the damage they might otherwise sustain 
from windy and boisterous weather. They feed on the 
devil’s-bit scabious, and on various kinds of marsh 
grasses; eating only the opening leaves as they come up, 
which renders them sometimes difficult to find. This 
they do only while the sun shines; for if, in the very act, 
the sun becomes hidden behind a cloud, they immedi- 
ately cease; but, on the return of the sun-beams, they 
recommence their operations with great voracity. 
Painted-Lady Butterfly. -(PI. 56.) The butterfly 
may be said to consist of three parts; the head, the corse-* 
let, and the body. The body is the hinder part, and is 
composed of rings, which are generally concealed under 
long hairs with which that part of the animal is clothed. 
The corselet is more solid than the rest of the body, and 
in which the fore-wings, and the legs are fixed. They 
have six legs, but make use of only four; the two fore 
feet are covered by the long hairs of the body, and are 
sometimes so much concealed, that it is difficult to dis- 
cover them. The eyes of butterflies have not all the 
same form; in some they are the larger portion of a
