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 

 (Fig. 286). 



T h e larvae 

 vary greatly in 

 habits ; but a 

 large proportion 

 of them are leaf- 

 rollers (Fig. 287). 

 It was this habit 

 that suggested 

 the name Tor- 

 trix (Tor'trix) 

 for the typical 

 genus, from 



which the names of one family and of the 

 superfamily are derived. A large proportion of the rolled 

 leaves found upon shrubs and trees are homes of Tortricid 

 larvae. But it should be remembered that the leaf-rolling 

 habit is net confined to this family.
