The bean weevil is a very serious pest in theSouth. It is not so destructive in the northern states andCanada and it is from this region that a large proportion of theseed beans are obtained. The bean weevil (Fig. 41) varies considerably in. size butaverages about | inch in length. The general color is lightbrownish. The wing-covers are mottled with light brown, 58 MANUAL OF VEGETABLE-GARDEN INSECTS. Fig. 41. — The l^eaiiweevil ( X 9). dark brown, gray and black, arranged in narrow longitudinalstripes. On the middle of each wing-cover near the innermargin is a fairly distinct light gray longitudinal bar. Theexposed tip of the abdomen, the base and last segment of theantenna^ and the legs, except the hind femora below, are dullreddish brown. The hind femur is armedon the underside near the tip with one largeand two small teeth. The beetles appearin the field about the time the beans are inblossom and feed slightly on the surface ofthe leaves. In cool weather the beetles aresluggish, but in bright warm days they cantake wing quickly and fly to a considerabledistance. As soon as the pods becomenearly full-grown but while they are stillgreen, the females begin egg-laying. The female first gnaws aslit through the pod close to the ventral suture and by meansof her extensile ovipositor then deposits a cluster of eggs on theinside of the pod. The hol
