The Argent and Sable Moth is found in Northern and Central 

 Europe, Northern Asia, and America. It expands from an 

 inch and a quarter to an inch and a half. 



The wings are white, with black transverse lines composed 

 of more or less confluent spots, arranged as follows : — The 

 base is black, usually intersected by a white line or spots ; 

 then comes a black band spotted with white ; and on the 

 hind margin is a black band more or less divided by a white 

 zig-zag line. The fringes are chequered with black and white. 



The larva feeds on birch and sweet gale. It is dark brown 

 with a black dorsal line, and a series of horseshoe-shaped 

 golden-yellow spots on the sides, connected by dots of the 

 same colour, so as to form a chain. 



The pupa is formed between leaves, and is at first shining 

 yellow, but afterwards becomes reddish-brown.
