This species, known as the apple root borer, has recently been investigated 

 b>- Brooks. Eggs are glued to the trunk close to the ground and the larva bores 

 directly through the bark to the cambium, and then through the cambium down 

 the trunk to the ground and outward through a convenient root, finally entering 

 the solid wood of the root where much feeding is done. 



Seems to live on shadberry {Amelanchier canadensis) (Austin). Feeding 

 on leaves of thorn, shadbush and chokecherry (Blanchard). On leaves of 

 Oxydendrum (Fiske). Larva attacks apple, pear, wild thorn, wild crab and 

 ser\'ice (Brooks). From leaves of Pyrns and Amelanchier (Frost).
