The Drinker Moth is found throughout Europe and Northern 

 Asia. It expands from two to two and a half inches, the 

 female being considerably larger than the male. 



The antennae are brownish in the male, and strongly pecti- 

 nated. The head and thorax are brown, and the abdomen 

 brownish -yellow. The fore -wings are obtusely pointed, 

 brownish-yellow shaded with darker, with a rusty brown, some- 

 what curved, transverse line near the base. From the apex an 

 almost straight line, bounded on the outer side with lighter, 

 runs obliquely to the inner margin, and in front of the hind 

 margin is a dark brown zig-zag line. In the centre is 

 a whitish or yellowish, elongated, oval, or reniform, spot, 

 surmounted by a dot of the same colour. The hind-wings are 

 coppery brown, with an indistinct dark band. 



The female is yellowish, though ochre-brown varieties are 

 occasionally met with. The markings are similar to those of 

 the male. 



The larva hibernates, and may be found full-grown in May
