LUNA MOTHS 
A green North American moth with tail, allied to the English Emperor- 
moth 
or crescent-shaped spots in the middle of 
the wings of some of the moths represented 
on this page and the next. These are 
very characteristic of the emperor-moths, 
and there is often a transparent spot in the 
centre of the concentric markings. Two 
other North American species of this family 
are shown in the photographs on page 719, 
rather under natural size. The second of 
these, the CECROPIA MOTH, is represented 
withitscocoon. This moth has occasionally 
been captured in England, having been 
introduced either accidentally or by design. 
A year or two ago a specimen was brought 
to the Natural History Museum at South 
Kensington which had been caught in the 
street close by. During the summer many 
foreign butterflies and moths may be seen 
alive in the Insect-house at the Zoological 
Gardens, Regent's Park, and several of the 
photographs given inthese pageswere taken 
from specimens living there in the summer 
of 1901. The largest of the emperor-moths 
is the great ATLAS MOTH of North India, 
the largest of all known butterflies or moths, 
which occasionally measures almost a foot 
across its reddish-tawny wings.
