The Strawberry Crown Moth {^geria rutilans Hy. Edw.) 



On the Pacific coast straw- 

 berries, blackberries, and rasp- 

 berries are injured by a whitish, 

 cylindrical borer, three fourths 

 of an inch long when mature, 

 which burrows in the crown of 

 the plant. The adult is a 

 clear-winged moth, resembling 

 a wasp. Remedies include sub-

 the removal and destruction of 

 infested plants.

 the roots.
