Two generations are known to occur in the mid-Atlantic States; three generations occur in South Carolina; and four generations occur in south Georgia and Florida. Since damage is usually most severe during July and August, very early maturing bean varieties and fall plantings may be grown with little injury. Planting susceptible crops in raised beds creates an environment that is less than ideal for root maggot eggs to hatch because they prefer cool, moist soil. All bean leaf beetles, however, have a black triangular-shaped spot on the forward margin of the wings. C. Tobacco thrips. Figure 8.
