The Leaf Rollers and the Leaf Mmers 



We are not to judge the importance of a moth by its size. The 

 codlin moth, the grain moth and the clothes moth, none of which 

 measare more than a half inch ajross the expanded wings, have 



made a far greater impression 

 upon the world than have the 

 magnificent luna or cecropia. How- 

 ever, not all the moths are so 

 iniquitous as those mentioned 

 above; many of them are exqui- 

 sitely beautiful and have captivat- 

 ing life-histories. 



The entomologists, who are not

lacking in imagination, have a 



pretty custom of ending the scientific names of these small moths 



in "ana" or "ella." Those whose caterpillars have the leaf- 



rolling habit are the "anas" ; the one that rolls the currant leaf is 



C. rosana; the pine leaf tube-builder is L. poUtana The midgets 



of the moth world, the Tineids, whose caterpillars are leaf miners 



and case bearers are the "ellas;" the one that mines the white 



oak leaf is L. hamadryadella; the one mining apple leaves is B. 



pomifoliella; tremendous namies for such tiny creatures !

The Leap Rollers 



If we look at the young basswoods, we find 



perhaps many of their leaves cut across, and the 



flap made into a roll and likewise fastened with ^ ^^^'.^^^^r,

silken ropes. The witch-hazel, which is a verita- 

 ble insect tenement, also shows these rolls. In fact, we may find 

 them upon the leaves of almost any species of tree or shrub, 

 and each of these rolls has its own special maker or indweller. 

 Each species of insect, which rolls the leaves ,is limited to the species 

 of plant on which it is found ; and one of these caterpillars would 

 sooner starve than take a mouthful from a leaf of any other plant. 

 Some people think that insects will eat anything that comes 

 in their way; but of all created animals, insects are the most 

 fastidious as to their food. 



Some species of leaf rollers unite several leaflets together, while 

 others use a single leaf. In the case of the sumac leaf-roller,
