MOUNTAIN TREES 



Other insects which are closely asso- 

 ciated with the oaks and which may well 

 invite our interest are the tiny leaf 

 miners which make those curious wind- 

 ing, serpent-like markings and blister- 

 like blotches on leaves by eating out the 

 spongy tissue just beneath the leaf-skin. 

 These little galleries which vary in shape 

 according to the species of the miners 

 inside, are made by small, white, much 

 flattened, wedge-headed grubs of teneid 

 moths. Now you will often notice near 

 the end of the miner's tunnel a small 

 enlargement which looks like a serpent's 

 head. This marks the point at which 

 the caterpillar changed to a pupa. In 

 some cases you will find a hole showing 

 where the larva came out of his mine 

 and went to the ground to pupate. Many 

 of the Tineids hibernate in the fallen 

 leaves, in which they pupate and then 

 transform into adults the next summer. 



The Tineids are our smallest moths 

 and include such injurious species as the 

 clothes moths and carpet moths. Near
