SNOUT-BEETLES AND GRUBS EATING LEAVES 165 



characteristic work of 



the larvae of the clover 



leaf-weevil. The grubs 



themselves are not apt 



to be seen, for they 



work only at night and 



he concealed close to 



the base of the plant 



during the daytime, 



but the edges of the 



leaves will be found 



eaten out in regular 



scallops. The full- 

 grown larva is a half 



inch long, dusky green, 



with a lighter stripe 



down the middle of 



the back. 



In July or August 



the adult beetle is to 



be found, feeding on 



the leaves of the plants. It is one third of an inch long, dark brown 



in color but lighter on the sides, and covered with short hairs. 



Eggs are soon laid by the 

 beetles, the young grubs feeding 

 for a short time and then hiber- 

 nating near the plants just 

 below the surface of the soil. 

 No direct measures of con- 

 trol are feasible. Badly in- 

 fested fields should be plowed 

 and seeded to some other crop. 



Damage is seldom serious until
