( Cotal'pa lanigera — Linnseus.)

 ■ Fig. 77. — Goldsmith Beetle — color, 

 rich metallic yellow. 



This beetle (Fig. 77) measures about 

 an inch in length. The female deposits 

 her eggs in the ground, and these 

 hatch into white, six-legged grubs 

 which closely resemble those common- 

 ly known as white grubs; they feed upon 

 the roots of various plants, and in this 

 way are sometimes very injurious to 

 strawberry patches. They spend sev- 

 eral years in this their larval stage, and finally assume the pupa 

 form in the Fall, and are changed to beetles in the following 

 Spring.
