Insects 



"The bob white eats insects in every month of the year. Moreover 

 the large proportion of injurious insects habitually eaten renders the 

 services of this bird more valuable than those of many birds whose 

 percentage of insect food, though greater, includes a smaller pro- 

 portion of injurious species. Conspicuous among the pests destroyed 

 are the Colorado potato beetle, twelve-spotted cucumber beetle, bean 

 leaf-beetle, squash ladybird, wireworms and their beetles, and May 

 beetles. Its food also includes such weevils as com billbugs, imbri- 

 cated snout beetle, clover leaf weevil, cotton boll weevil: also the 

 striped garden caterpillar, army worm, cotton bollworm, and various 

 species of cutworms; also the corn-louse ants, red-legged gTasshopper, 

 Rocky Mountain locust, and chinch bug." (9) 



The most important insects added by my experiments are the squash 

 bug, plant lice, the cabbage butterfly, cankerworms, codling moth, 

 the Hessian fly, the mosquito, stable fly, and the typhoid fly.
