Si6 ENDEMIC AND INTRODUCED FAUNAS 



The larva of a native moth — Cacoecia excessana, Walker — forms a 

 tough netting and covers it mimetically with dead leaves, under which 

 it lives. Mr W. W. Smith has noted it as common on the surface 

 of the leaves of the laurel {Prunus lauro-cerasus), and on many of 

 .the cultivated fruit trees. Other examples of interaction between 

 native insects and introduced plants are given in the next chapter.
