Host: Orange, lemon, lime, mandarin, and cabuyao. 



Injury: Injures the blossoms of orange and lemon. 



Biology: Eggs deposited in the calices o;' peduncle of the flower; larvae upon hatch- 

 ing bore through the inclosing parts, often destroying the calyx, pistil, and ovules; 

 pupate within the flower and also in leaves or forks of twigs or branches. C. F. Baker 

 states that in the Philippine Islands "the larva of this moth lives just beneath the rind
