Insects Injurious to the Apjyle. 



69 



wings have also a similar greenish tinge. The abdomen is of 



somewhat similar hue and crested, with two more or less darker 



spots near the back. It appears in May, June and July. The 



female places her eggs on the fruit trees and they remain there all 



the winter. In spring the larvte appear and enter the opening buds. 



The caterpillar is pale yellowish-green with a rusty-red line down 



the back, the divisions between the 



segments reddish and a line at the 



sides of a yellowish -green. The dorsal 



line varies in colour and size; some 



have it broad, others narrow or almost 



absent, sometimes it is dark green, at 



others almost purple. These larvae 



are most noticeable in April and May 



and are all mature by early June. 



They then fall to the ground and 



pupate in a cocoon of earth. The pupa is deep red at the tail end, 



the thorax and wing cases yellow, tinged with olive.

TllEATMENT. 



Early spraying arsenate of lead. The same spraying used for 

 Winter Moth should suffice. It may be pointed out that if these 

 caterpillars are in excess grease-banding need not be persisted in.

THE CODLING MOTH. 



{Carpoccvpsa 2)Oinonella. Linn.) 



Everyone knows a maggoty apple and avoids it unless they can 

 get no other. Yqw people, except fruit-growers and gardeners, know 

 anything of the cause, however. The " maggot " is the caterpillar 

 of a small moth, one of the Carpocapsidcc, whose larvse live in fruits or 

 seeds. If we turn the Codling Maggot over on its back we shall see 

 that below are legs, these are of two kinds, the first six are horny 

 and pointed, and then in the middle of the body are four pairs which 

 are soft and fleshy " false legs," and there is another pair behind. 

 Thus the Codling Maggot is a true caterpillar, like that of the Cabbage 

 White Butterfly. It is very important for growers to notice this, as
