The food plant records in the literature are of no great sig- 

 nificance ecologically because the character of the leaves of trees 

 growing in open places and in forest and the physical conditions 

 surrounding them are so different that a species feeding on a 

 given tree in the forest might not feed on the same tree in the 

 open and vice versa.
