THE CANADIAN NATURALIST. 
ROYAL TIGER-MOTH. 
( Ardia Virgo.) 
F. — The lustre of the spots and marks on many moths 
and butterflies, rivals the glitter of the precious metals : the 
silver spots on the wings of the Spangled Orange moth are 
exactly like those on some of the Fritillaries. 
C. — Some of the Zebra Hawk-moths^ which I enclosed in 
a box^ laid several eggs^ which were round, rather flat, 
pearly white, of about the size of a small pin's head. They 
were not deposited all in a place, like those of a Phalcena, 
but singly, all about the box, slightly stuck on. In about 
seven days they produced the young caterpillars, which, when 
hatched, were about one-fourth of an inch long, all white, 
except the anal horn, which was black, straight, and half as 
long as the body. Not knowing their food, I tried them 
with a great variety of leaves, and at length found that they 
would eat those of the ash ; and I afterward found a solitary 
egg of this kind attached to the leaf of an ash tree. I sus- 
pect the caterpillars would have very materially altered in 
form and colour, as they became mature ; but I had not the 
satisfaction of proving this, as every one died in a day or 
two after being hatched.
