THE LOCUST TWIG BORER. 

 Ecdytolopha insiticiana Zell. 

 ■Order Lepidoptera ; Family, Tortricidae. 



The inj ury occasioned by the larvje of this Tortricid is very common, 

 and is characteristic for the species. In many sections a large proportion 

 of the young locust shoots are seriously injured, and may be even killed, 

 "by the galls produced by the larvae in their borings. 



The adult female probably deposits her eggs between the thorns or 

 in the axils of the tender side branches of the current season's growth. 

 When the larvae hatch they bore down into the tender tissues, and their 

 activities cause, in a majority of cases, a gall-like swelling of the stem.
