The dates of the appearance of the perfect insect are 
from the latter end of May, through June and July, and 
even in August and September. One on December 13. 
The caterpillar is of a green colour, dotted with yellow 
and with seven slanting yellowish-white lines on the sides. 
The tail is yellowish above, and reddish underneath. 
The date of the appearance of the caterpillar is in 
August and September—August 22nd. 
It feeds on the different species of poplar, as also on the 
sallow, the laurel, the laurustintis, the aspen, and the birch. 
This species varies considerably in colour as well as in 
size; some specimens being of a yellowish brown, more or 
less deep, and others of deeper or lighter grey. One has 
been known without the red mark at the base of the hind 
wings, and four instances have occurred in which the 
wings on one side have been those of the male, and on the 
other those of the female, and the antennae likewise 
divided in the same way. It has been known to pair 
with S. ocellatus and S. ligustri.
