HOW TO KNOW THE BUTTERFLIES 



Our English Cousins call it " The Camberwell 

 Beauty." 



The eggs are laid in clusters and are often 

 placed in a compact mass around a twig. Very 

 beautiful eggs are they ; but Madam Antiopa is 

 a careless mathematician. Sometimes her egg 

 is eight- and sometimes seven-sided, the areas 

 marked with ridges in a highly decorative man- 

 ner, as may be seen in Plate XXV. As soon as 

 the caterpillars emerge from the egg they arrange 

 themselves side by side, close together, heads just 

 reaching the edge of the leaf on which they feed, 

 making an orderly eating class in the green 

 school-room. They are sociable little fellows for 

 all their bristly spines, and live together all their 

 lives and often hang up near each other when 

 they change to chrysalids. Once when a brood 

 was reared in our insectary it was discovered that 

 when a noise was made on a tin pan or anyone 

 with a bass voice sang, these caterpillars would 

 rise as one, lifting the front half of the body 

 from the leaf, and would shake or tremble as if 

 they had the palsy. They were not disturbed 

 by a very loud noise, but within a certain range 

 they would immediately respond, and when all 

 were thus trembling and shaking they presented 

 an absurd spectacle.
