near relative, the cherry-tree leaf -roller (A. cerasivorana), festoons 

 the branches of the wild and cultivated cherries with its large nests 

 of leaves fastened together with silk, in which a whole brood of 



the yellow larvae live and transform. Another 

 group of this family includes the well-known 

 codling moth (Cydia pomonella), the worst pest 

 of the apple grower, and the eye-spotted bud 

 moth (Tmctoccra occllaua}, which bores in the 

 young buds 

 of the apple, 

 as well as nu- 

 merous other 

 larvae which 

 bore in the 

 buds, termi- 

 nal twigs, 

 fruits, and 

 seeds of va- 

 rious trees 

 and plants. 



The pyralids. The third family, Pyralidac, 

 includes some half dozen families of quite di- 

 verse appearance and habits, among which are 

 the larger "micros," some of the largest having 

 a wing expanse of one and one half inches and 

 being larger than the smaller forms of the 

 macrolepidoptera. Many of the caterpillars be- 

 longing to this group attack low-growing vegeta- 

 tion, the garden 

 web-worm (Lo- 

 xostcgc simila- 

 //>) being one 

 which now and 

 then becomes a 

 pest in various 



parts of the country, attacking gar- 

 den crops, sugar beets and young 

 cotton, and corn. The full-grown
