LEAF-MINING INSECTS 



leaf-mining species. These have been designated as the 

 Imported turnip leaf-miner {Scaptomyza flaveola Meig.), 

 the Imported cabbage leaf-miner {Scaptomyza graminum 

 Fall. 4 ), and the Native cabbage leaf -miner {Scaptomyza 

 adusta Loew.). Another species Scaptomyza terminalis 

 Loew., may prove to be a leaf -mining form. Sturtevant 

 (1921) believes that S. flaveola Meig., does not occur in 

 America stating that this species is referable to S. adusta 

 or S. graminum.

The native cabbage leaf -miner Scaptomyza adusta Loew., 

 is common in New York State. It mines chiefly in the leaves 

 of the cruciferae although pea and a few other plants are 

 attacked. The adults occur abundantly during the summer 

 and are frequently taken by sweeping fields or roadsides 

 with a net. 



* Duda 1921 proposed a new name, S. dislicha for this species.
