OAK COMMUNITY. 



As a rule an insect that feeds upon one species of oak will be 

 found to feed upon the other species. Therefore I shall list 

 the oak feeding species under the one oak community. This 

 rule does not hold good in every case, as many of the insects 

 are limited to a single species of oak. The oak supports a 

 larger number of insect species than does any one tree. ■^|_ And 

 yet we find the giant oaks monarchs of the woods.
