open. These sprayings would also catch the bud moth larva, 

 which is a serious pest. 



The Apple-leaf Skeletonizer (Canarsia hammondi Riley). 

 This is a small, brown caterpillar, about one-half of an inch long 

 when full grown. It feeds on the tissues of the leaves beneath the 

 silk web, causing the leaves to look corroded and rusty. The larva 

 is marked by four black dots just back of the head, two on the 

 first segment and two on the second (Fig. 121). The pupal stage 

 is passed on the leaf, and there are probably two or three broods 

 during the season. The adult is a grayish moth with a wing ex- 

 panse of one-half inch. 



Control. These caterpillars are easily killed with arsenical 

 sprays. They are also attacked by several parasites. 



The Well-Marked Cut-Worm 

 (Noctua clandestine, Harr.). De- 

 scription: The caterpillar of this 

 species resembles somewhat other 

 cut-worm caterpillars and its life 

 history is more or less like that

of other representatives of the family. When full grown, it 

 is from one and one-half to two inches long. It is dull brown, 

 gray, or blackish, often tinged with greenish, and is more or less 

 marked longitudinally with dots and dashes. These markings are 

 inconspicuous so that the caterpillars harmonize with the color 

 of the soil. The head and thorax-plate are horny, and are reddish 

 brown in color. 



The moth has dark fore-wings, gracefully marked with darker 

 or lighter spots and narrow bands, and has lighter hind-wings. 

 The moths, unlike others of this group, fold their wings over the 

 back when at rest.
