The eggs are laid in the soil, each female laying about seventy- 

 five eggs, which hatch in about three weeks, and the larvae tunnel 

 in the roots of corn and other plants for nearly four weeks, 

 pupating in an earthen cell from which the adult beetle emerges 

 about a week afterward. 



The adult beetle is somewhat larger and stouter than the striped 

 cucumber beetle, and averages about 7 mm. in length. The wing- 

 covers are greenish yellow, marked with twelve black spots 

 arranged in three transverse rows, and varying in size. Thorax 

 bright yellow, head black. Legs, except thighs, and antennae 

 blackish. 



Where abundant enough to cause injury, the same remedial 

 measures used against the striped cucumber beetle should be 

 practiced. ♦ 



The Squash Lady-Beetle. 



Epilachna borealis Fabr. • 



Nearly all of the lady-beetles are carnivorous, and are con- 

 sidered beneficial because they feed upon injurious insects such 

 as plant lice and scale insects. The squash lady-beetle, however, 

 is an exception, and feeds upon the leaves of cucurbitaceous

 of this group. 



The adult beetles hibernate under bark or in other sheltered 

 places, emerging in June, and toward the end of the month lay
