beetle is a small greenish to yellowish beetle with black stripes down the 

 sides of the wing covers. The beetles pass the winter living in sheltered 

 places and begin to feed on the new elm leaves in the spring. When the 

 leaves are fairly well grown the female beetles begin to lay eggs. The larvae 

 or grubs hatching from these eggs also feed on the elm leaves, transforming 

 into beetles in early July. A second generation follows. 



Control is best accomplished by spraying the trees with a lead arsenate 

 and water mixture, one pound of powdered lead arsenate to fifty gallons
