cutworm is a 



dark-colored worm, usually some shade of gray, with faint 

 stripes running lengthwise of the body. The body is soft and 

 easily crushed. The adult form of the cutworm is a moth. A 

 moth looks like a butterfly, but it is not so brilliantly colored 

 and flies at night instead of by day as the butterflies do. 

 Moths are attracted into our rooms at night in the summer- 

 time by the lights. The cutworm moth lays its eggs on the 

 stems and blades of grass or clover in the summer. When the 

 eggs hatch the larvae go to the roots of the plant and become 

 partly grown before cold weather. They remain in the ground
