THE BEAN BEETLE. ( K j)il (U'luirv C()rru pt(t 
This is by far the most destructive bean pest in Colo- 
rado. The mature insect is a beetle about one-third of an 
inch in length and yellowish to rusty brown in color with 
sixteen small black spots on its wing covers. The beetles 
deposit their yellow eggs in patches on the underside of the 
bean leaves. The grubs are light yellow in color and are 
covered with stout branched spines. The insect, in all 
stages, feeds upon the leaves and green pods of the culti- 
vated beans and particularly wax !'>eans. Lima beans are 
seldom badly eaten by them. See b'ig. 40.
