The Winter Moth (Cheimatobia brumatd] and 

 the Lime Looper Moth (Hy hernia defolaria). 

 The caterpillars of both these moths are very 

 destructive to the leaves of elms, limes, and 

 willows, but particularly to the buds of the 

 apple tree. When full-grown they descend to 

 the ground, where they cover themselves and 

 become chrysalides, from which the moths 

 appear from October to December. Being 

 almost wingless, it is by no means difficult to 

 prevent their ascending the trees by painting 

 a band of any sticky substance around the 

 stems of the trees that it is expected they 

 might attempt to crawl up. We have said 

 more about this in the chapter on fruit trees. 



The thorn fly (Aphis crattegt) attacks whole 

 hedges or brakes of quick, especially those in 

 the nursery border, as a rule the younger and 

 more healthy plants first falling a prey to its 

 depredations. Sponging with tobacco water 

 or almost any of the prescribed solutions will 

 rapidly exterminate the fly ; but such work is 

 laborious when a large brake or long hedge of 

 the thorn has to be gone over. 



The cockchafer (Melolontha vu/garis) is
