Superfamily TORTRICINA (Tor-tri-ci'na). 



The Tortricids (Tor tri-cids). 



The Tortricids are generally small moths ; but as a rule 

 they are larger than the Tineids. They have broad front 

 wings, which usually end squarely. The costa 

 of the front wing curves forward strongly 

 near the base of the wing. When at rest the 

 broad front wings fold above the body like a 

 roof. The moths are variegated in color, but 

 are usually brown, gray, or golden rather than 

 of brighter hues. As a rule the hind wings 

 are of the color of the body and without 

 markings. In the venation of the wings they 

 differ from the Pyralids in having subcosta 

 and radius of the hind wings widely separate 

 beyond the end of the discal cell ; and from 

 the Tineids in having the second anal vein 

 of the hind wings forked towards the base
