142 ARTICULATES: INSECTS. 



yellow dots on the back, and two rows of yellow spots 

 across the wings; the hind wings are tailed, and have 

 seven blue spots between the two rows of yellow ones, 

 and an eye-like spot of an orange color with a black 

 centre. The female is much larger, and has fewer 

 yellow spots on the upper surface. The caterpillar 

 lives upon such plants as the carrot, parsnip, celery, 

 and anise. It is" green, with a band made up of yel- 

 low and black spots on each ring. When touched, it 

 thrusts out from the head a pair of soft, orange-col- 

 ored horns, which have a disagreeable odor. In July 

 it reaches its full growth as a caterpillar ; then it seeks 

 a sheltered spot on the side of a building or fence, 

 spins a tuft of silk, fixes its hind feet in it, then makes 

 a loop of silk, and, passing its body through it, rests 

 upon it as a support ; soon it casts its caterpillar skin 

 and becomes a pupa or chrysalis, Figure 266. In about 

 a fortnight the chrysalis bursts open, and the perfect 

 butterfly, Figure 267, appears. 



WHITE, AND YELLOW BUTTERFLIES. 



The Philodice, or Yellow Butterfly, expands about 

 two inches, and is common in fields and by roadsides 

 throughout the summer. The White Butterfly, or 

 Pieris, is of about the same size, and is also common. 



NYMPHALIS BUTTERFLIES. 



These butterflies are remarkable for their beautiful 

 colors. The Misippus Butterfly has the wings tawny 

 yellow, veined with black, and a black border spotted 

 with white, and the fore wings have near their tips a 

 black patch spotted with white, and on the hind wings 

 there is a curved black band. The caterpillar lives on
