The Bristly C'lrTwoRM 

 Mamestra renigera Stephens 



The range of the bristly cutworm is from Georgia and New 

 Mexico northward to Colorado, Ontario and Nova Scotia. It 

 is mainly a grass and garden pest, feeding on clover, grasses, 

 turnip, corn, cabbage, chic- 

 ory, comfrey and garden 

 flowers. It feeds chiefly 

 on the roots. 



The winter is passed as 

 partly grown larvae, which 

 cause the most serious in- 

 jury in April and May. The 

 full-grown caterpillar is 

 about an inch in length, 

 yellowish gray marked with 

 two distinct black lateral stripes. Scattered over the entire 

 body are many black and yellow bristles — hence its common 

 name. Pupation takes place in the ground. The moth has 

 an expanse of about an inch. The front wings are rich brown, 

 the reniform spot green margined with white and the orbicular 

 spot inconspicuous. There are on each wing a distinct quadrate 

 green patch on the hind angle and an elongate one near the 

 middle of the base. The hind wings are smoky, darker towards 

 the edge (Fig. 174). There are two generations annually. The
