THE LIGHT-BROWN APPLE MOTH. 67 



CHAPTER X. 



THE LIGHT-BROWN APPLE MOTH. 



(Cacaecia responsana.) 



Order : Lepidoptera. Family : Tortricidce. 



This insect, which is known to growers by the name of 

 the Australian Apple Moth, is a pest of the very worst 

 kind, and in many cases its ravages have been of a most 

 serious nature. 



In appearance it is totally unlike the true Codlin Moth, 

 although as so little has hitherto been known here of the 

 perfect insects of either, it has in many cases been taken 

 for the imported Codlin Moth, Carpocapsa pomonella. 



The habits of this insect are very similar to those of the 

 true Codlin Moth, inasmuch as the eggs are deposited in 

 the calyx of the young apple ; the larvae however, as a 

 rule, do not always penetrate so far as the pips, and 

 owing to this circumstance the grub will sometimes 

 remain a long time within the ripening fruit, the mode of 

 attack being shown in Plate V., Fig. 1. The larva or 

 grub is of dirty light-green colour, the perfect insect being 

 light-brown, with slightly barred wings, which are about 

 three-quarters of an inch across, that is in good female 

 specimens; and the illustration (see Plate V., Fig. 4), 

 which has been drawn from nature, will explain all with- 

 out a lengthy description being necessary. 



Mr. Oliif speaks of another species, C. postvittana, of 

 this genus of moths as being very injurious to apples ; but 

 the insect from which our plates have been taken is 

 certainly not the above one, although I believe the larger 

 species, C. postvittana, to be here also, but to what extent 

 the damage done by it has, I believe, not yet been 

 perfectly ascertained.
