Fig. 294. — Squash-vine Borer — colors, white 

 and brown. 



The eggs from which these l)orers (Fig. 294) 

 hatch are dej)ositcd on the vines near the roots, 

 and as soon as hatched the young borers penetrate the stems 

 and devour the j^ith, frequently occasioning the death of the 

 vines. They reach their full growth in Autumn, and usually 

 enter the earth and construct a sort of cocoon in which to pass 

 their transformations ; sometimes, however, they pass through 

 their transformations within their burrows. They pass the 

 Winter in the pupa state, and are changed to perfect moths in 

 the following Spring.

 domen is deep orange, marked with black.
