 with grey-black ; hind marginal region faintly rippled with 

 grey lines ; cilia white, clouded with grey. Hind wings

 so in front, with a bristly look from the unusual prominence 

 of the hairs ; pure deep green ; head shining black, mouth 

 brown ; dorsal plate shining black with a narrow green

April to June on Viscum album (mistletoe), at first mining 

 the leaf, then spreading its burrow and clearing out the 

 whole substance of the leaf, leaving the skins thereof so that 

 a leaf appears to be a mere bladder of skin. If necessary 

 removing to another leaf and commencing the same process 

 towards its tip. This is one of the very few known instances 

 in which a Tortrix larva is a leaf-miner during its whole 

 larval state. 



Pupa yellowish brown or reddish brown ; having short 

 wing cases and a long tapering mobile abdomen. On a 

 cocoon of white silk placed in open network in any interstice 

 under bark or lichen. (Dr. Wood.) 



The moth sits during the day on the trunks of apple trees
