Cherocampa elpenor: the Large Elephant Hawk- 
Moth (Plate XVI., Fig. 7).—A fairly common species, 
but local, and to obtain fine specimens it is best to hunt 
for the larvae and rear them. They feed on Willow- 
Herb, both E. angustifolium and E. hirsutum, and also 
on Bed-straw, in August and September. The moth 
appears in May and June, and comes to flowers and 
light. Expanse of wings, rather under 24 inches, 
Smerinthus ocellatus: the Eyed Hawk - Moth 
(Plate XVI., Fig. 8).—The only British hawk-moth 
with eye-like markings. Not uncommon, and is easily 
reared, The larva feeds in autumn on Sallow, Poplar, 
and various fruit-trees. By submitting the pupa to a 
steady artificial heat—say about 70° F.—the perfect 
insect will emerge in from fourteen to twenty days. 
All the “ hawks ” are very susceptible to this treatment, 
and it avoids any risk through keeping the pupa 
over the winter. In Nature the moth appears from 
May to July. Wing expanse, about 34 inches, 
Smerinthus popult: the Poplar Hawk - Moth 
(Plate XVI., Fig. 9).—Common everywhere in June.
