 bailey i Wooton and Standley" (specimen label); F. filifera Chabaud, F.

Distribution (map 6). — Largely due to its ability to subsist on 

 nearly every species of Yucca east of the Rocky Mountains, Tegeticula 

 yuccasella is the most mdely distributed species of the Prodoxinae. 

 In the United States this species occurs as far north as southeastern 

 Canada (southern Ontario) and Massachusetts, west to North Dakota, 

 thence south to southern California. In Mexico, T. yuccasella ranges 

 over the Mexican plateau to as far south as Tehuacan in the state of 

 Puebla.
