Yellowish-green beetle with 12 black spots on the wing covers. The cucumber beetle eats foliage but is seldom abundant enough to cause yield loss. Damage by this insect may be significant if many other defoliating pests are present. The margined blister beetle is black with gray margins on the wings. The threestriped blister beetle is yellow or orange with dark stripes running the length of the body.
Blister beetles eat foliage.
Severe defoliation sometimes occurs on field margins. These insects tend to congregate and damage is confined to small spots. White tufts of hair are present on the sides and tip of the abdomen. Japanese beetles eat the leaf areas between the veins and cause skeletonizing of the leaves. Although this insect is frequently found in soybeans during June and July, it seldom causes yield loss since defoliation is usually light and plants recover from damage before blooming.
