Food habits. This caterpillar appears to be a general feeder, 

 it having been recorded by Beutenmueller on elm, maple, sweet 

 gum, etc. It is rather common on black birch, feeds upon poplar 

 and, as stated above, the eggs may frequently be observed upon 

 apple and pear. It has also been recorded on lilac and chestnut. 



Remedial measures. Should the caterpillars of this species 

 become abundant they could probably be easily controlled, as in 

 the case of other leaf feeders, by timely spraying with a poison, 

 preferably arsenate of lead.

MAPLE LEAF CUTTER 

 Paraclemensia acerifoliella Fitch 



Plate 18 



This peculiar insect was excessively abundant on the estate of 

 Dr Wilby Meyer, North West Bay, Lake George, in the town of 

 Bolton or North Bolton. The infestation though local was 

 severe and included perhaps twenty-five acres. Some trees had 

 their foliage very badly injured, there being in each leaf a number 

 of oval holes and much of the tissue between dead, because of 

 skeletonizing by the larva. The work is rather characteristic, 

 since the caterpillar reaches out from its oval case, eating all 

 that is within reach and then migrates to another spot. Infested
