 The Common Footman is found throughout Europe and 

 Asia Minor. It expands about ij^ inch. 



The fore-wings are dark leaden-grey, with a yellow stripe on 

 the costa, gradually narrowed to the tip. The hind-wings are 

 of a uniform pale yellow. 



Common Footman. 



The larva is black and hairy, without spots. There is a 

 reddish stripe on each side above the legs extending from the 

 fifth to the eleventh segments. 



It feeds on lichens growing on walls and trees, especially 

 on those of the poplar. 



This species is very similar to Z. complana (Linnaeus), the 

 type of the genus, which is a scarce Moth in England, and 

 may be distinguished by the pale stripe on the costa not being 

 narrowed, but running in equal breadth throughout, to the tip 

 of the wing. Most of the other British species of Lithosia are 

 more or less local.
