It feeds on Jungermannia^ and various lichens. 



The larva is reddish-brown, and is contained in a brownish-

This genus and its immediate allies present the character 

 istics of the Family in the highest perfection the long, narrow 

 fore-wings, with the costa nearly straight, and the broad 

 rounded hind-wings. The fore- wings are usually pale-coloured, 

 varying from yellowish to pale grey, generally with a paler line 

 on the costa, and sometimes with one or two black dots. The 

 hind-wings vary from whitish to pale brownish-grey. 



We have several closely-allied species in England, of which 

 the best known is the following :
